internal/external issues in 4-land: nagios and IMAP on the iPhone,
web to be able to pick up .ics files in iCal, ability for the lappy
to rdiff-backup back to home while away, etc.

I'll not argue pain, since that's all subjective. Mine's fairly
static after initial spinup, so, I can't judge how it'd be for
others' sites. Add in that I did the remote/local publishing
a little inelegantly and want to redo it. But, to the point of
On my todo list is a nagios check I've not written due to laziness;
give it a zone name, 2 nameservers, and optional keys for the AXFR's,
let it tell you if resource records appear in one and not another.
Right now, it's too easy to cheat and just hand verify zone consistency
