i don't have anything against that when ua registers it tells its unique
id so that registrar can discard the old ones.

what i was trying to say that outbound does not bring any help to
implementing redundant sip infrastructure, where two active proxies
could have worked together each with its own ip address.

what comes to nat traversal, what are the problems with contact
rewriting?  so far it has worked quite well for me.
