Correct; you can set up the system on the network poller exactly as if it
were a full xymon server running xymond locally, then disable [xymond],
remove the 'NEEDS xymond' from [xymonnet], and enable [xymonproxy] with
--server= in the relevant tasks.cfg stanza set to the IP of the real
server.

Theoretically, it should be pretty transparent for both your xymonnet
instance as well as any pollers or clients reporting in to it.
