With QuickDNS 3.5, there's an AppleScript to do just that. You'd
really only need to use it once, though.

Sorry, but it's a bit unclear to me what you mean.

When you create a new zone, if you're connected to both master and
slave servers when you create the zone, you can configure all servers
in one step.

They would rarely get used. They are cached for additional queries
from the same resolver, but only for that zone. So if a resolver
needs to look up two different pieces of data from one of your zones,
it may ask the extra servers that aren't listed in the domain's
registration record.

In general, though, you should list all of the servers that have
authoritative data for the zone in the domain's registration record.

No, there isn't. You do in fact need to configure one of your servers
to be a slave for each of the other person's zones, and that
configuration occurs one zone at a time. You can, however, use
AppleScript to automate this.

Which is why you should tell them.
