I would prefer to just go with a dns server with a DB backend but others are naturally resistant, and like their zone files but not the slow speed they bring with them (generally speaking).

How much time does zonec currently spend parsing and compiling the 
database?  A quick test run shows that parsing and compiling the 
database is about 2.5 times slower than loading the database. So that 
will be about the maximum amount that can be gained with some kind of 
incremental updates.
