The model is not really bringing benefits, is just another fantasy.
Honestly I could think of just few restrictions/amendments/additions to the base SIP RFC3261 and the next 10 following it to have very good and simple model for im, presence, file transfer, desktop sharing a.s.o.
Anyhow, you know that I'm not contrary to drop an existing protocol and making a new one if the existing specification is a pain ;) But in this case I just think that MSRP is the way to go.
