> The issue arises when you try to multiplex multiple "applications" on a single AOR and, I gather, a single dialog. Standardizing such usage would seem to require a new higher level application framework on top of sip. One such framework that comes to mind is IMS.

I am using such single dialog scenario with MSRP and I am not able to find any issue with it. Can you please expand what issue you are referring to.
