This is not a bad idea at all, but why use a daemon to listen to a file 
when it can just as well listen to a socket or a pipe? Have the daemon 
either run some program to set the lights or do it itself. Borrowing the 
code from Nagios to parse the objects.cache file should be a no-brainer.

Or better yet, write a NEB-module to handle it. That way you get access 
to the Nagios configuration when it's already parsed and all should be well.
