I guess the question is whether there is any case where a websocket 
makes sense in a bundle. My first thought was No. But on further 
thinking, ISTM that *in principle* it would be possible to run RTP over 
websocket. And then, since it makes sense to bundle RTP, it could also 
be possible to bundle websocket.

Of course to do this would first require a binding of RTP to websockets. 
Since you can already run RTP over TCP, it should be possible. (And 
easier, since the websocket provides the framing.)

Whether anybody would find reason to do so is another question. I doubt 
we will see it any time soon, and probably never.

*For now* I don't think there are any cases where it makes sense to use 
websocket in a bundle.

I'll leave it to Suhas to figure out what classification applies in this 
case.

	Thanks,
	Paul
