I am using the AS3 localConnection Class
to connect one AIR desktop application with another over a local network.
Can anyone tell me if it is possible to use localConnection to connect to more than 1 device, or is it strictly 1:1 ?

Can we control multiple DSC-QX100 cameras using the Camera Remote API SDK from an iPad OS7?
The objective is to cause multiple cameras to "snap" picture at the exact same time. Perhaps each camera has an address (serial number)...can the software communicate with all cameras at the same time using multiple addresses? Need is limited to still photos and so-called fast, rapid photography. Video not necessary.
If so, how?
Unfortunately you can only control one QX100 lens at a time. This is because the lens connects over WiFi and you are limited to only a single WiFi connection at once on an iPad. It may be possible using a desktop PC with multiple wireless cards installed but that would be the only way.
As the Sony rep said, there's no way to do this with "officially supported" techniques.
The reason for this is that the camera acts as a WiFi Access Point (AP) - so while multiple devices can connect to it, most mobile devices can only connect to it and not anything else (since iOS and Android don't support connection to multiple APs simultaneously). This is also why you can't use other network interfaces when connected to the camera. (I don't know about iOS, but Android always prioritizes WiFi over cell network data, for example.)
Android devices have a feature called "WiFi Direct" that provides more flexibility in terms of peer-to-peer interconnection, but iOS does not support WFD. The QX100 DOES respond to WFD invites, and you can accept a pairing request with (if I remember correctly) a long-press of the shutter button. However, the official app only supports normal WiFi AP connections.
I have not yet attempted to see if using Sony's remote API in combination with the (unsupported but apparently present) WiFi Direct capability works.
More info on Wifi Direct and Android can be found at http://developer.android.com/guide/topics/connectivity/wifip2p.html
Marlin SONY, I disagree, wifi is Ethernet and by definition can handle multiple devices on the same network. If you run a phone or iPad as a hotspot and connect multiple devices, it works.
Multicam Switcher Basic is an example of a free app that supports cutting together multiple camera angles live. Unfortunately the app is still being developed so features like third party camera support isn't included, but it does show what is possible and awaits development.
I think this should be possible. Apps like CollabraCam™ (Multicam Social Video Production) or RecoLive MultiCam prove that is possible to use mulitple cams simultaneous.
I need someone too to develop an App to be able to use "two" sony dsc-qx for 3D shoots. Please, if You know how or who can do this contact me email#3-d.re
I'm working on a project that recognizes faces.
The idea of the project is as follows:
I have an arduino connected with a GSM/GPRS shield. This gives the arduino the ability to connect to the internet. I have also connected a special shield for a camera.
Now I managed to take photos from the camera and upload them using FTP to a webhost.
The problem is that I won't the web host to be able to recognize the face with a pre-saved SQL database and reply via FTP to the arduino with the name of the person recognized in a Text file.
Of course for that matter, I have SD card with it's shield connected to the arduino.
I would love to hear your opinions on how will that work if it's possible in the first place?
I've seen so far some application fourms done in VB to do Face recognition. Is there a way to upload these fourms -btw they are regular fourm not ASP.net - to the host and somehow use it to do the FR?
Thanks,

I want to make my iPhone app display on a Mac's screen, kind of like AirPlay does with other machines. The only way I have heard to do this is, although I do not like it, turn the iPhone into a server. Unfortunately, I cannot figure out how to do so. I also wanted to set it up in such a way that my Mac automatically detects it. I have seen a similar setup in the game Chopper 2. My Mac app will have a simple timer that fires every few seconds to look for the iPhone, in the same way that Chopper 2's "Find iPhone" button does.
Is there a simple way to turn the iPhone into a server, or start a "session" like Game Center does?
One last thing: I know it is somehow possible, because another app I have actually gives my iPhone a web address at the click of a button. It is called the Dicenomicon, if you want proof.
First there is no easy way to redirect your display to Mac, even if you made it a server of some kind.
Second, to discover or publish customized services on WLAN, you may want to refer to the samples on Bonjour:
CocoaHTTPServer: a simple TCP/HTTP server.
WiTap: an app that discovers and connects to services of the same kind on WLAN by Bonjour.
I'm not really sure what you mean by "server", because there is no way to share the screen of an iPhone using the official SDK, although this is possible by jailbreaking.
It would be possible, however, to send data back and forth between the Mac and iPhone, and display the data on the iPhone, on a Mac. Using that data, you could try to recreate the interface on the Mac. All of this could be accomplished using sockets. A class that might help with that would be cocoaAsyncSocket, which makes network programming a lot easier.
The auto-discovery of iPhones on the local network is achievable with Bonjour. Without getting into too many details, NSNetService would allow you to publish a service for your app from an iPhone, and NSNetServiceBrowser would allow you to find that service on the local network from the Mac. From the NSNetServiceBrowser, you could establish a socket connection with the iPhone.
Good luck!
You might want to take a look at the GameKit APIs, I know they do something similar between two iOS devices.
http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/GameKit_Guide/Introduction/Introduction.html
I just want to know that is it possible to communicate two different apps in different device. Like I have a sample app in device A App name A and in another device B i have a app B I want to share some things between them. I came across to GameKit framework in iOS but I made a app when it is installed in both device they communicate succesfully but what if apps are different and what is the size limit of the data to send it over bluetooth in iOS.
Any idea how to implement this feature?
Two different apps can communicate via Bluetooth using GameKit as long as they both agree on the protocol (i.e. if you wrote both apps, or you know what protocol the other app is using).
There's no limit to the amount of data they can exchange, although there is obviously an upper limit on bandwidth (bytes per second).
Does that help?
I have an app which displays an image when I say some word, and the word is from my dictionary which I had exclusively created for the app.
Now I want that image displayed on my friends iPad simultaneously, when it shows on my iPad. Is there any way for that?
Thanks and regards,
Christy
If both iPads are in the same local network, you can use cocoahttpserver to run a HTTP-Server on every device and announce the services via Bonjour. Once a new picture is available, that devices connects the server on the other devices and informs it, that new data is available. The second device than will connect the server running on the first device and download the picture.
the advantage of this approach: the protocols you are using are well-know and a lot of additionally tools are available.
But you can also have a similar, more downlevel appoach, where you design your own network protocol. In that case I'd use Asyncsocket
Use synchronize image with both ipad using internet or use APN to notify that image is ready.
