I've been playing with WebRTC and reading about the way it works, but I'm still quite ignorant of what's really going on under hood when it comes to peer connections. The way that the streams are routed, won't it choke if there's too many participants in a video conference without some sort of central server, if they all have to connect to one another?
Has anyone experimented with this? Anyone care to take a guess at the threshold for your average broadband connection?
They will definitely choke whatever it is that you are doing.
You will need a central server, but that is up to you - WebRTC only deals with the media transport and communication part - you need to take of the signalling of it all on your own. To that end, you can add a media server to handle multipoint conferences and have it do the orchestration of the conference.
