Hm... good question. I think we already support multiple data sources,
right? Is that how we handle VERSION.BIND queries now?

This is exactly what we need.

In the long term this needs to be configurable somehow. People will want
to change this without adding/removing data sources (because if you
remove then add to move something to the end of the list, there is a
time when you are not answering for that data source).

Yup, that's my thinking too.
