Well, our system is the about 49th uncommon system on earth, currently
(http://www.top500.org/dlist/2002/11/). ;-)

Forgive me for answering before researching this matter very
thoroughly (it's past midnight here). I'm not sure I understand what
you mean by monitoring server, distributed server and the hosts. 

What I sense is some kind of "cascaded nagios server": I set up my
main nagios server for the whole system minus those special hosts. 
Then I set up a second nagios server (or a second instance on the same
machine) to run inter_check_delay_method=n (not 'd'; I want all checks
at the same time) on those special servers. Now I need a method for
the main nagios server to get the check results from the the second
server. Worst case would be that I end up with two independent nagios
servers, in an ideal world it would be possible to merge those two. 
What do you think? 

Fortunately I'm not under time pressure, as the system monitoring was 
due roughly half a year ago, a couple of weeks more or less won't make
much of a difference. And since it's for internal use only I will get
away with an inelegant, but working solution...
