You could do this using MySQL as your backend and doing MySQL 
replication between your dns/database servers.

MySQL replication is relatively simple in concept, each database can 
slave off another, so that any changed made to the master are replicated 
out to the slave.  In order to have this work bi-directionally, database 
server A is configured as a master, with B slaving off A.  A is then 
configured to slave off A, completing the loop.

There's plenty of online documentation on configuring MySQL replication, 
and I use MySQL replicated back-ends in our PDNS environment.
