Gonzalo,

I am *interested* in this work. (I was working on something similar when 
I first got involved with sip 10 years ago.)

And while I have been opposed to new mechanisms for coordination between 
the two ends, I do see need for mechanisms to further coordinate the 
federated pieces at the end where federation is occurring - such as 
getting a subsidiary device to answer the call from a sibling device. (I 
just don't see that as an alternative to a sip dialog for establishing a 
media session.)

However I *don't* have cycles to allocate to this work now, beyond 
general review and comment.

	Thanks,
	Paul
