Following my discussion with Brian West, here is what we look for:

We want to be able to have a similar functionality to mod_conference's video-bridge but also to be able to broadcast video from 1 member to all the other members in the conference. We wrote our own mobile client using Google's WebRTC stack, we are going to use iSAC (we are currently using it) and VP8 for video, hence, we do not need to transcode, just pass through the video.

Please let me know if you have any questions!

Thanks,

Adam
