I'm more concerned that whatever approach we adopt makes it possible
for applications to configure themselves automatically using the info
in the DNS.  Most likely people will configure manually until the pain
of doing so gets great enough that it's worth the hassle to implement
autoconfiguration for HTTP, SMTP et al., but we owe it to them to make
the autoconfig possible when they're ready to bite the bullet.

Mark is more or less right that CNAMEs do what you want, although they
don't deal with A.B.C where each of A, B, and C have variant forms.
