I'd take a security-based approach. I do not feel too comfortable with
a server holding valueable or vital data is open to connection from
the nagios host, which, as a host running a web interface, might be
more easily compromised than the actual server. This is a minus for
NRPE. With NSCA, the actual server would initiate the connection to
the Nagios host which decreases security exposure.

otoh, NSCA has a "gap" in data flow as nsca_send wants to see the
output in a different format than the plugins put out. There are a
bunch of shell scripts around that "translate" between the plugin and
nsca_send, but these are like foreign objects in the nagios setup in
my feelings. I think that there should be a "glue binary" written in C
that calls the plugin and then hands over the results to nsca_send.

Greetings
Marc
