We use this system now.  Our method is this:

* Two pdns servers, one primary and one secondary
Both running mysql and gmysql back end
* One machine running mysql with a web front end and PDNS Admin Console
for PDNS

* The PDNS console machine operates as the mysql master and both the
master pdns and the slave pdns operate as slaves to this master database

You will need to google: mysql master slave replication.  We've been
using some form of the above implementation for many years.  Works great!
