I actually didn't mention SIP as the dereference protocol.  What I am 
asking is which dereference protocol with a subscription mechanism are 
you going to specify?  Or should implementers assume XMPP for this 
feature? :)

Thanks for the clarification, but I was talking about the dereference 
being orchestrated via subscription rather than polling.  I wasn't 
really talking about the conveyance itself, other than to ask how a 
conveyee is to know what to do with the reference.

I know, which is why I asked...
