I think the question is simply whether or not we can create such an RTP 
stream without acquiring a MediaStream via getUserMedia(). roc's 
MediaStream Processing API certainly provides a way to do this. Chris 
Rogers' Web Audio API doesn't seem to provide MediaStream objects that I 
can tell, but I assume that's something that could be fixed.
