You could have the first authoritative nameserver listed with your registrar as the dyndns address, then do your dns locally for your domain. Two scripts on http://sleekfreak.ath.cx:81/technology.html allow this, regenerating the zone file every time the address changes. The two scripts run under client/server model presently. They would have to be merged or called sucessively to make it work on one host.
