I presume the concern is about Windows clients.  A Windows client will 
attempt to register with any name server that is authoritative for a zone.  
The name server need not be the master for the zone.  I don't understand 
why both name servers need to be the "master" name server.  This disables 
your ability to synchronize the zone data.
