Yup.

Cool, that's exactly what I'm talking about.

I basically have the Nagios schema finished, so if we could agree on one
and then send it to the nagios maintainers for inclusion or something,
that would be great.  OTOH, I'm interested in your Cricket schema; have
you sent it to the Cricket maintainers?

I'm definitely interested, and I expect that as we get a more complete
system (and maybe someone releases some docs) more people will get
interested.  We could take this offline, maybe.

Very cool.  I don't know what percentage of time I'll be allocated to this
in the near future, but I'm already generating Nagios configurations out
of LDAP, but they don't include any service checks.  This month and in
January I plan to add nmap and traceroute functions to the nagios objects
so that they'll automatically built port checks and IP dependencies, but I
don't know if I'll be able to release them.

Heh.  If you're company would like to hire me to work on this for them,
I'd love to come spend a few months in Australia. :)
