standardized maintenance tool

[Brian Noecker]

We're looking at implementing a zone file maintenance tool.  We'd like to
integrate it with existing database backends, namely, Oracle or Postgres.
We'd also like to have a web interface, preferribly one with different
levels of access for subdomains, etc.

We have 30 - 35 zones, but plan to handle more.  We'd like to implement a
free version if possible.

Does anyone have any suggestions?

Thanks in advance.
