Sure, this makes sense. This still leaves me with no mechanism for 
setting up PTR records when using the Samba built in DNS server though.

Maybe this is all set up to only work with DHCP, in which case I would 
want to dig into using reservations so that machines have a 
deterministic IP address. I know this isn't necessary with Dynamic DNS, 
but I haven't come around to trusting this yet.
