Eliot, The only relationship SL has to renumbering is the ability to have connections persist while a network is intermittently attached to the public network. Renumbering is already solved in terms of the simplicity of moving hosts from one address space to another. The complex issues to work on are the places like firewall & router configurations that have explicit addresses in them. What is not fixable is the fact that apps will break if you change an address out from under them. This is a fact the app developers complaining about the complexity of scoped addresses continually overlook. The assertion is that all a network needs to do is change the addresses in use when connecting. Never mind that every local use app will break on every one of those events. That is not an acceptable approach.
