   But, at a certain point, wouldn't you start spreading the zones over more servers,
   for performance reasons, if nothing else? I just get the feeling that raising the
   zone limit is simply going to permit more clueless admins to dig themselves into
   deeper holes, and then this list will be flooded with "Why does my named take so
   long to reload?" posts...

Actually, we're in the process of consolidating from about 8 servers to 4
(one hidden primary/secondary and 3 published servers -- see the thread
about GTE Internetworking submitting lots of domain modifications to NSI).
When they get overloaded we'll add more, but for now we'll just keep adding
memory to the ones we have.
