Merlin would do exactly that if you set one of the nodes as a poller
but having all hosts assigned to it. When the poller goes down, the
master will by default take over checks for it.

Merlin is actually pretty well documented, but as textfiles that you
have to read the oldschool way. If there's anything you find lacking
from the HOWTO document or the README, please let me know and I'll
amend it.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
