You can use any authoritative for the zone name server. One of the masters
is good enough.

slaves you can just set few masters for each zone. For example:

zone "" {
           type slave;
           file "/var/named/";
           masters { master_ip_address; master_ip_address; ... };

When named receives NOTIFY for a zone it will check one by one the servers
from the "masters" list.

Hope someone has gone through this trauma.
