Have you not heard of NSCA?

Using NSCA would be much better from the point of view of both 
standardization and Security.

Having ssh access from unix clients to the server feels dangerous. I 
would infer that this ssh access is automated and hence probably uses 
unprotected ssh keys. This is a bit of a back door where all roads lead 
back to your nagios server. You should strongly consider switching to 
NSCA for that.

On windows, if you want it as a passive check, I think the only way 
would be to use something like Nc_Net which I believe supports sending 
passive service checks to the nagios server. I haven't used it 
personally so I can't vouch for it (it requires that you go around 
installing the .NET framework, which makes it quite unportable and not 
easily deployable since even the .NET silent install is not silent but 
gives a popup, it would an ugly hack to try to use Wsh to try to catch 
that to automate the install, hence I use NSClient++ which is easy to 
deploy and I don't have to deal with any installing more).

If there is a port of send_nsca which is the passive service check 
client then I suggest you use that to call whatever check_plugins you 
want and sent the result back to the nagios server. You will have to 
install an NSCA listener on the nagios server of course but this is not 
difficult and it gives you passphrase and encryption protection.

The idea for this plugin would not include the passive service check 
send, as I want it to remain portable and independent of all Nagios 
execution mechanisms so that anyone can use it in any setup with any 
technology they are using for remote checks.

 From a design perspective, the remote execution mechanism and the 
actual check_plugin should be separate and modular so you can mix and match.
