interested in being able to do incremental updates (appending/inserting new data

again.  Is it feasable with the current setup? or will significant kludging be
in order to facilitate this? 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.
