Absolute names work too, of course (e.g. the MX record for each zone apex points
to foo.bar.example.com. regardless of zone).

I sort of wish that named.conf supported a "batching" syntax to facilitate this
usage, e.g.

zone "example.com", "example.net", "example.org" {
    type master;
    file "db.example";
};

(Yeah, I know, BIND is open source, patches welcomed...)
