If you make before break, this *might* work.  You would need a trigger to cause the other side to start using the new address, which I don't think that we have.  It might be possible for a client to receive packets from a different remote address and start sending on that address, but how does it decide to switch over?  That suggests a new signal of some sort, which costs.  Also, many firewalls and NATs will stomp on packets from a new address, which would prevent spontaneous migrations at the server side.
