I had considered this as a suggestion as well but felt it was messy due
to the need to duplicate all the host and service definitions on both
machines but with different names plus a third definition for each for
the cluster check. Templates should make it easy mandate which
definition was active/passive on each machine but the duplication just
wouldn't scale well IMHO.
