Hehe. Tbh i don't want to, and i do not have the time to play around 
with some demo configs ;-)
I'd rather trust his expertise being an "old" nagios user in that case. 
Though, I am more into plugins and addons removing some inner core logic 
stuff which could behave different. Probably just a dev's taste who 
cannot rewrite the inner core.

Imho the Business Process Addon might be overkill for your use case. So 
my way of doing it would be

- try Assafs proposal
- play with check_cluster or check_multi
- add bpaddon and rules

stopping when i found a suitable solution.

That of course. It's just a matter of getting it done now, but hoping 
for the future providing better solutions. Plus, setups like yours are 
interesting for special test cases for the final release :-)

Kind regards,
