Yes, fine. And who's gonna tell your tunnel partner your address has
changed and their SPD must be changed? Do you have a protocol for doing
that in a standard way? What if you have a Cisco router on the other side?

That's why I say it's not going to work. The tunnel definition on BOTH
endpoints must be synced before the tunnel can be re-established. IPSEC
tunnel mode can only be established (without external software) between
fixed addresses. That's why Cisco & MS use L2TP, which is actually PPTP
over Host Mode ESP.
