80:20 basically. It is broken, but not so much that its annoying.

If a new host comes in (ie doesn't exist in the hash), the passive 
service check result will be rejected by Nag, and sooner or later, I 
will notice it and deal with it.

Basically, I expect only traps or messages from hosts I am aware of and 
configure Nagios and SEC accordingly (this is at least part reasonable 
since I configure routers and influence config of switches).

The same is true of the basic Nag distributed mon set-up: its necessary 
to configure the central site Nag with the services and hosts that it 
expects to receive passives from (all this is true of Nag 1.x only; 
don't know about 2.0)

These questions are good; they prob should go to either lists, so you 
can get these opinions moderated/tempered/flamed. Rest assured, you are 
not dealing with a very clever or knowledgable person.

Yours sincerely.
