I'm not saying anyone would do it, because it's kind of madness.  But it's
a theoretically-possible madness.

Here's a simple proof:  we know that unbundled m-lines can have transports
connected to different hosts (with different DTLS certs, etc).  And those
hosts can be browsers, and those browsers would be different

The congestion control might not work well, but ICE will.
