How to implement group video chat using vLine API

I am new to WebRTC and vLine API. I need to implement a Group Video Chat just like Google Hangout using vLine API and PHP. Please suggest if any example or solution available or how to go about it?
Thanks
Tanjum
We have a PHP example on GitHub: https://github.com/vline/vline-php-example (More examples available here).
With the current API you can implement group chat with a mesh topology where each user establishes a connection with the other users (using person.startMedia() on each person you want to include in the conference). Due to both bandwidth and CPU, this won't scale well beyond four people or so.
We have a better conferencing solution in development (that won the Best Conferencing Award at the WebRTC Expo), but it's currently only available to a select group of beta testers.

iOS third party maps

I'm building an iOS app using MapBox for maps and MapQuest for directions data. Are there any limitations as to what an App can use or display in terms of third party (non MapKit) map data? Will an app that displays maps and directions from other sources be approved for the App Store..?
I am the developer of the MapBox iOS SDK. Many apps have been approved by Apple with alternative maps and/or directions. Some examples include:
http://thesilenthistory.com
http://www.mapofthedead.com

http://mapcraftapp.com

Additionally, all but the last use MapBox.
Here there are other alternatives that can help you on both sides:
skobbler iOS SDK- they offer offline maps, route calculation, turn-by-turn navigation and a free tier plan.
cartotype - they offer vector data, maps and routes can be displayed as integrated map layers or overlays.

Exploiting the voice chat feature in Game Centre to create a Skype-like voip app?

So one can use AVAudioSession and GKVoiceChatService classes to set up voice chat in ones application like this. Now, is it possible to extend the same feature to creating full featured voip apps the sole purpose if which is device-to-device voice chat.
Assuming this is possible, would Apple approve non-gaming apps that uses this feature?
They do allow other game center features for use in non game center apps. They allow the bluetooth/ad hoc networking. Similar apps to bump use it, so why not?
