Yeah, I've scratched my head on that issue before. Eventually I gave up
after reading the mod_ssl docs:

The most common way to do it is to use IP aliasing to assign multiple
IPs to your server, once for each SSL vhost. I just did a search through
the apache-modssl mailing list, and you can actually do multiple unique
SSL name-based vhosts on the same IP, _if_ use use separate ports for
each. That might be acceptable as well... ie is accessed via, is, etc.
