Do initial negotiation with a datachannel only (note: this may cause 
problems with use of local IPs/ports and force calls to be relayed to 
start).  Then add audio and video to the call (can use the DataChannel 
to pass the offer/answer, note! -- and we may now end up with a direct 
connection instead of TURN (I hope)).

You'll end up with m=application, m=audio, m=video.

Downside: no DataChannels (yet) in Edge (and forced use of TURN probably 
to start).
