We had actually looked at this same thing about a year ago. There is a
module that replaces the db backend in bind 9.x, but there was some
reason why that wasn't a good thing... I forget now... I think it might
have been a performance issue. (I seem to recall that performance was an
order of magnitude slower.)

I know that you mentioned bind specifically... But we also looked at
PowerDNS, and while we liked the functionality... We were really
concerned with how well a DNS that serves directly from a database
(MySQL) would scale and maintain the level of uptime we desired. (Not to
take anything away from PowerDNS, I hear it is a good dns server.)

We eventually rolled our own using a MySQL backend and a PHP script that
checks the database for updates every 5 minutes ("select count(id) as
count from zones where updated_".$server_id." = 1"). This allowed us to
have the zone transfer functionality without actually having to set it
up (both dns servers are technically masters for the zone in question).

I have that script if you are interested, unfortunately our web based
front end is integrated into our support application for our end users
and I can't unbundle it and still retain its functionality.

DJB's tinydns is even easier to use since once you make a change to the
master file, it automatically rehashes a cdb file which can easily be
rsynced to a remote computer... But then not everybody likes DJB and his
way of doing things...

Just some alternatives and my experiences with the problem...
