[Gossip-dev] telepathy roadmap and media streaming

[Robert McQueen]

I think abstracting stuff into seperate concepts of a video call and a
voice call would be unwise, because at least in Jingle calls, individual
streams can come and go during the lifetime of a call. Ie, you can be in
a voice call and plug in a webcam and then offer a video stream to
somebody. They could then go "oh yes what a good idea", and then plug
their webcam in, and upgrade the video stream to bidirectional...
There's a reason that the Telepathy API exposes the streams to you, each
with their own directionality. :)

Rob
