I assume that it is rather trivial (even since i'm using ndoutils and 
can lookup the service states in db) to get the service-states out of 
nagios.

I think check_cluster does something like this too, but it's used for
a different purpose.

What I'm really interested in, is, if there are any dangerous pitfalls I 
  could run in, when I use the service states to determine the host-state.
Has anybody ever used something like this ?
