As stated in the Google Talk for Developers site, you can use the provided APIs to build a client that connects to the Google Talk service.
I would like to know if it's possible (or it will be in the near future) to build a similar client to the google hangouts.
What we pretend is to build something similar to cloud print, that provides printing services to the cloud, but for audio/video streaming: a camera and microphone would replace the
printer.
Thanks a lot.
Talk and all the XMPP stuff is going to be put down soon.
The new Hangouts infrastructure is proprietary. It only has API to integrate Hangouts into web pages and applications, but no API or protocol to create an alternative Hangouts client software.
https://github.com/tdryer/hangups is a library that does exactly that, with a command-line client for Linux.
https://github.com/xmikos/qhangups is a PyQt-based cross-platform app that aims to provide an open-source alternative to the Chrome-based official desktop app. Unfortunately it's not working at the time of posting, but the author is investigating the issue.

If you want it free, you can develop it yourself, using WebRTC:
WebRTC is a free, open project that provides browsers and mobile
applications with Real-Time Communications (RTC) capabilities via
simple APIs. The WebRTC components have been optimized to best serve
this purpose.
See WebRTC Tutorial
On client side you use JavaScript (jQuery), and clients communication directly using browser, but you need server part and signaling mechanism, and you can use for example SignalR or Node.js.
As example you can look at my site: SignalRTC.
P.S. WebRTC works only on selected browsers, for example Chrome, FireFox, unfortunately not on IE or Edge.
I have some questions like how whatsapp server is working, though I read in internet, I want to understand much. And what is XMPP? how it is working, How can I send data through XMPP. how can I integrate XMPP with application, can anyone pls explain?
WhatsApp under the hood?
There are rumors WhatsApp uses a customized version of XMPP. Sources are closed so we can only guess.
Understanding XMPP will however give you all the tools to create your own WhatsApp clone.
What is XMPP?
According to Wikipedia (which hosts further references):
Extensible Messaging and Presence Protocol (XMPP) is a communications protocol for message-oriented middleware based on XML (Extensible Markup Language).
Which is to say that XMPP is an xml based convention for exchanging messages between parties. It's best known implementation is Ejabberd chat server.
XMPP can however be used for other things, among them the web of things.
How to send messages?
Assuming you want to create a chat application, you will need:
An Ejjaberd server up and running.
An appropriate xmpp SDK for you language/framework. Example: Smack for Java or agsXMPP for C#.
A good kick-starting tutorial about how xmpp works can he found here: part one and part two.
There is also the RFC which contains the most comprehensive documentation out there.
I need some guidelines here. I am creating an online booking system for my client that interfaces with QuickBooks on their internal network (desktop QuickBooks, not online).
Do I need to go the full "publish app" route? I do not wish to sell this app in the marketplace. This is merely a custom booking system designed and paid for by the client. It seems like I need to "publish" the app in the marketplace for them to be able to use it.
Are there ways around this?
Update 06/23/2015 - To connect to a desktop QuickBooks installation the SDK with the Web Connector is now the only recommended approach. Intuit is removing Intuit Partner Platform (IPP) integration to desktop QuickBooks.
For the SDK/Web Connector, you don't need to go through any publication process or anything like that. Just build the solution, and connector your client.
There's a pretty good overview of how the QuickBooks web connector works on our QuickBooks wiki.
The QuickBooks SDK download also includes a huge PDF with detailed documentation about how to implement SDK/Web Connector applications as well.
Does anyone know how to connect to Google Talk using GData API. IS there a better api for iphone development for connection to Google Talk? I have been looking thru the examples I downloaded for the API but I don't see any support.
This is what I have been looking at.
Google Talk uses XMPP, and it has no GData API.
I suggest you look at: http://code.google.com/apis/talk/talk_developers_home.html
Are there any initiatives to implement/agree upon a standard API for connectivity between web browsers and client hardware.
Example: The iPhone has a GPS/Camera/Accellerometer in it. It'd be very cool if my web app could communicate with them (rather than me having to write a thick ObjectiveC application).
The closest thing I've seen to that is the Android phone API, which lets your programs access its hardware (relatively) painlessly. Google's pushing for it to become the new standard, but its hardly the same thing as a web-app (which, by most definitions, runs entirely in your browser?).
The upcoming version of FireFox has an API to read your lat/long off a GPS device.
To add to my own question; Yahoo provides a geolocation service called FireEagle that could act as a mediator and provide similar functionality.
In essence the phone communicates with a central Yahoo server updating its location. Your web app can then determine your approx location from that central server.
