Sure, however I could use some clarification here. On one hand, the 
draft falls squarely in the middle of the overall "Plan" discussion we 
have and hence is highly relevant, but at the same time, if I understand 
correctly, the draft is not asking MMUSIC to do anything in terms of 
protocol development. Rather, if this approach is adopted, it would be 
more of an RTCWeb usage document specifying how one could use several 
different mechanisms (and possibly WebRTC APIs) to implement signaling. 
There doesn't seem to be a "mandatory to implement" mechanism for 
guaranteeing interoperability (in contrast to Plan A/B), but rather 
there are references to "app specific signalling" mechanisms, etc. Am I 
missing something here ?

No worries.
