I would hope that audio and video data would get sent using the 
ConnectionPeer mechanism, ideally UDP-based (though that protocol hasn't 
even been sketched out yet), not over TCP-based WebSockets.

But if we do want to send live audio data over WebSockets, then we're 
going to do a bunch of work, like adding microphone support to the Web 
platform. When we do that, we can easily add a live-stream-specific frame 
code that sends fixed size blobs of audio and/or video streams. The 
protocol supports that as an extension fine, without needing to define how 
fragmentation works today.
