The supermaster functionality works well for this. If you are using
PostgreSQL as the DB backend, you may want to consider using the
patch I posted to PDNS giving you the option to configure the zone
commit command. This allows you to use temporary tables to optimize
zone updates on the slaves. There are several samples included with
the patch.
