John,
Thanks. I've been trying to make this point for awhile, without (I
guess) being understood.
IMO all of these use cases can be solved by having the cooperating
devices on one end organize themselves and present one signaling session
to the other end. This can be achieved using existing mechanisms.
These are use cases of considerable interest. I can see how an
informative document that shows how to realize these use cases could be
useful. But I don't see any need for normative work.
Thanks,
Paul

I think the case where a participant in a call has audio on one device
and video on a different device (and similarly for other media) is an
interesting problem space. The use of two separate dialogs to the remote
UA to achieve this is not the only solution, and has the disadvantage
that it requires the remote UA to handle two separate dialogs, rather
than the normal single dialog for multiple media. With this solution,
the special needs of one side require special support on the other side.
There may not be incentive for the other side to provide such support.
