It is easily done with FreeBSD.  I had it set up on a home network, 
doing DHCP to update the DNS with the hostname of the client when 
activated.  That way, it was easier to network test certain devices.  Do 
a "man bind" (I think that's the man page, can't recall for sure, but it 
is there somewhere).

That is true.  If you control BIND, the world is your playground.  You 
might also want to take a look at SQLBIND, as it is BIND after being 
patched to run off of a database.  That could open up more options if 
you wish.

It means they aren't going to allow dynamic DNS updates to their DNS 
servers.  I work for an ISP, and the last thing I want to do is open up 
the DNS for dynamic updates.  That becomes a security nightmare.
