Perhaps powerdns is an option for you? It has some nice features regarding
these problems. There is the so called "native mode". Replication between
master and slave(s) is done by database replication (mysql/postgresql).
When running as slave for traditional nameserver you can define them as
'supermasters'. When the master send a notify to the slave, powerdns
creates the zone on the fly and does an axfr. Also, no more reloads - all
changes are effective immediately. www.powerdns.com / apt-get install pdns
