In all seriousness, while I think it must be exciting to build new
things, I think we have to stop building new servers.
This NIH syndrome is destructive. Who is going to maintain this code in
the long run ? We can barely maintain the code we have, adding new
servers seem to me like begging for problems later on.

What is wrong in building a BIND plugin and reducing the amount of work
to maintain to the minimum necessary for us ?

Sorry if I sound harsh, but these kind of things really trip me off ...
