I am the user where cyclops refers to.
Altough im not exactly the user, I am the builder and tester of the
platform and maintained it for a while.

I had the same goals as you, get rid of /djbdns/ by moving to powerdns
with tinydns backend and after that
change tooling so we can move to a mysql backend. I also tested with
tinydns backend acting as master and
mysql backend as slave. This worked flawless altough it took some time
and load before all records where transferred.

For the records,
I ran tinydns backend about 3 months in production. I found some bugs in
the beginning, but they where adequately solved by cyclops (and his team

As you can see I have some rich experience with the tinydns backend.

If you like, we can look if I can help you out on the office. I'm a
freelancer and always available for good assignments.
I suggest you contact me at my email address if you like the idea
(Business is not something for the maillist).
