Well, part of the issue is how "muted" is transported to the receiver, 
how fast that occurs (basically it can't be fast enough other than "next 
frame of video sent") - and the receiver may not be a WebRTC client.

You could simply stop sending, but that can cause problems for some 
receivers, and they can't distinguish between that and a routing or 
packet loss - after how many not-arrived frames do you give up and put 
up "Muted"?  Etc.  (ICE should keep the ports open, at least.)
