Thoughts about a custom plugin

[Paulus, Jake]

Using NRPE, the check scripts (like check_ping, etc.) would be run on
"DUAL HOMES Machine" but kicked off by NAGIOS Host.

I'm not certain this is intended for exactly the application I have.
perhaps
it is, and I am misunderstanding it. let me clarify my application a bit
with an ASCI diagram:

The Nagios host can get to the dual homed machine, and I can use all the
standard plugins to get status from it. What I want to do is get status
from
the TARGETS. 

Are you suggesting using NAPE running on the dual homed machines? And
somehow
using this to query the targets? The web page you pointed out makes me
believe that NAPE is intended to allow me to execute checks on a
reachable
machine, by using local scripts there, rather than having the NAGIOS
machine
use the more traditional check_* plugins.

Am I confused?
