when on ambigiuos ground, your best bet is to clear it with the author
ahead of time.  if you really want to get out of this issue, instead of
"an apparently undordered manner", i'd suggest encoding it a meaningful
but non-nagios-defined order (maybe XML), where you wouldn't need nagios
source code to reassemble it into a meaningful object, and would be
generally useful in its own right.  or, as you're already doing, using
a db as a go-between.

well, if your business is built around an open source application, i
don't have that much sympathy if you discover your percieved business
model doesn't match with the open source ethos/license :)

i remain to be convinced that changing the nagios license to allow
proprietary derivative works / modules will in any way benefit the users
of nagios.  but then again, i'm not the author so maybe you'll have some
luck with ethan.
