Some of us already automate checking versions of DNS servers in our
network monitoring systems, but finding out when you really need to
upgrade vs a minor feature update is still a bit of an art form; as
Paul said, most DNS servers only get restarted very infrequently, and
I do not get paid to run around upgrading nameservers just because
someone added a new feature we don't use/need anyways.

My own experience is that the ClamAV (I think) model of e-mailing a
notice when important things need attention is useful, but that does
not always scale too well to a larger organization.

I'd *like* to be able to have better ways to monitor nameservers, but
some of what would be most useful really requires support in the code
itself, or from ISC.

With 24 million small businesses in the US alone, that's way too many apples.
