[MMUSIC] Merging ICE aggressive and regular nomination (was Re: [tram] Comment on draft-williams-peer-redirect-01: might it not converge?)

(Moving this discussion to MMusic.  I suggest further discussion drop the tram list, unless it cycles back around to a TURN-specific issue.)

This is equivalent to using regular nomination, but saying that an endpoint can send media on any Confirmed candidate pair, not just the Selected one, right?

5245 says that an ICE endpoint MUST be prepared to receive media on any candidate, but only sends on the Selected candidate pair.  I don’t know if this means, in practice, that ICE-bis could change to the behavior I’ve described above and still be backward compatible, or if there’d need to be some sort of ice-option negotiation to indicate that this early media (oh, dread phrase) is acceptable.
