I'm sure lots of people are thinking along the same lines, but there's a basic problem with that approach: if you have a transient connectivity problem that *doesn't* involve changing addresses, you lose many or all of your outstanding sessions unnecessarily. In many cases, that's not a problem, but for the cases where you need unattended recovery, it probably is.
