Go back in the thread and re-read my mail :-)

We discussed this a bit on the Asterisk developer's meeting in Anaheim
and I said that I wasn't really sure whether we would benefit from
implementing this, since there's no other part of Asterisk that does
this and the core is very device centric. The only way I can see a
solution that agrees with the Asterisk architecture is to make sure we
have a full peer for each device that registers. Mikael's solution
bypasses the peer, which means that call limits and other peer functions
is no longer supported, but his channel might not have that implemented
(yet), so it might not be a problem in his implementation.

As Jeremy said, I usually solve this kind of functionality with a SIP
proxy, that supports multiple registrations and SIP forking much better
than Asterisk at this time.
