We did this and it works fine as you might expect.  Perhaps we should put 
it up on bugs.digium.com, but it wasn't a big change.

To my mind it doesn't make much difference where the phone is registered 
to.  Registration is just a way to find out the contact info (IP address 
mainly) for the SIP user.  Once we have that on one machine, in principle 
it can be used on any machine.

The only issue may be that NAT is open from the machine to which the phone 
originally registered, bt not from others.

So in our application we didn't bother to track which machine took the 
original registration.
