Imagine it, a burst of traffic on the Hesiod mailing list. I think I
subscribed to this list in 1993 or 1994.

I'd suggest restricting zone availability using views in BIND.
Because I just can't resist, here's a little Hesiod story. In 1993 I
was a network engineer at an ISP (Digex, Inc), and our main office and
datacenter (such as it was in those days) was in an office suite above a
Chinese restaurant in a shopping center in Maryland.
In a fit of boredom one afternoon (which was unusual, with our
workload in that startup company environment) I implemented a scheme by
which the menu from the Chinese restaurant was encoded in Hesiod records
in our nameserver, using delimited fields in the TXT records that
implemented a linked list in Hesiod records. I wrote a little C program
that allowed one to look up menu items step through them individually
via the linked list scheme, etc.
Fun stuff. :-)
