I'll look into it... Will probably require ugly kludges (a script that
regenerates the SPD and Racoon configuration on-the-fly if the WAN IP
address changes) that I don't really like to see in m0n0wall, but if
there's no other way, I'll consider that. Maybe this weekend, but I won't
make any promises.

That's right. We'll have to introduce another means of identification (not
the remote address) for this scenario; preferably something that is
supported by most commercial firewalls (pseudo host name?). Otherwise
there's no way for racoon to tell which tunnel configuration the
connecting dynamic endpoint belongs to.

Mmmmh, I'll have to check out the peculiarities of Racoon's configuration
file (and upgrade Racoon to the latest version while I'm at it) and see if
there's support for it.
