1) Can you provide some more information as to specifically what you
mean by "testcases"?  Is nagios going to be initiating these test
cases or is something else?

2) Do these tests happen during a regularly scheduled time interval? 
The scheduled downtime feature would work for that.

3) At first thought, the ssh methods seems not quite as complex as you
described -- dealing with keys will be as annoying as it has to be for
your security-mindedness, but the command you need to run is a
one-liner and wouldn't require any daemon running on the nagios
server.  Just ssh in using a key and echo a command to nagios via the
command file.

4) Have you considered using the cgi's + some Apache authentication
method?  I haven't actually looked into it, but anything you can do
through the web interface you should be able to script.

There is more possible that I had previously thought:
