Just because you don't use it, doesn't mean that others won't.  For example,
my employer manages thousands of virtual services distinguished by IP address
for which some of the protocols (e.g. SSL, anonymous FTP) are virtualized by
IP, and POP3 virtualization piggybacks on that just because it can.

We then support user at domain for those cases where the customer simply doesn't
want SSL or virtual anon FTP.

I think it's a good idea.  Do you have patches, Vegard?
