That moves the data across but what about inserting it the zone files and
resetting named?
Have you though about how you're going to implement the security on this? I
suppose using your inetd server you could just use TCP-wrappers to
authenticate the remote system (make sure that you're PARANOID). I once
wrote a challenge based authentication system using bash, /dev/urandom and
md5sum (therefore anybody can...).
Using 'scp' to move the data across might be a neater idea, then a cron job
to rebuild the zone files (set to run at the same interval, or less than
the zone refresh time).
Dynamic DNS might be a lot easier. If I were to have an IP address for my
CM (which of course would only be required if it were to be used as a
server and thus in conflict with NTLs terms of use) I would use dynDNS.org.
