I was trying to help a coworker last week, and I suggested just such a
thing... BUT he has RCN and evidently they don't assign hostnames of any
sort, or at least they didn't for him... :-/
As a side note, IIRC you aren't supposed to have an MX record pointing to
a CNAME. It may work now but it may not work in future versions of BIND.
Another such feature is underscores in host names. It violates the spec,
but currently works. The maintainers have said that eventually, they will
remove the functionality that allows them.
[Whether or not they actually do remains to be seen... Lots of people use
underscores.]
