DNS cluster

[J Sloan]

I would love to see what you have - I've been looking for a better way
to keep master copies of our dns zones, and had been thinking about a
mysql solution, but haven't found the time to write the functions to get
the data into the database, or to create well-formed files using data
from the database.
