Hi,

>>> By "RTCP transport in the offer", I mean separate ICE candidates generated for a RTCP ICE component, the original problem that I was proposing to solve.

> I was there and I don't recall this decision; I spent half an hour discussing this exact point in rtcweb based on a scenario you suggested (namely, a new PC created from a fork). The discussion ended with some interest but no consensus, which is why we are discussing it here in email...

Ok. My recall was that there was no support to do the "optimization" forking, i.e. allowing identical port values (and, in this case, also rtcp-mux) already in the initial offer for a PC, and therefor we were not going to do it. 

I'm glad if I'm wrong :)

> For sanity's sake, can you make it clear that you support this proposal?

Yes, I do.

Regards,

Christer
