[Nut-upsdev] Multipathed monitoring of an UPS

Given that some UPSes and other devices manageable by NUT may have
several means of connectivity simultaneously, such as USB/Serial and
SNMP, it may be useful to utilize several connection methods to the
Moreover, a couple of master servers with connection to the
engineering VLAN (where an SNMP UPS is present) might provide
equivalent "access" to the UPS data for the slave systems without
access to that VLAN.
I believe the key idea here is to have a grouping of MONITOR
rules (or perhaps a new similar keyword) that would state that
a number of "ups at host login pass" tuples correspond to the same
set of "N powersources fed". As long as at least one "data path"
provides non-stale data, we consider that the UPS information
is available for this set of powersources.
Does this idea sound sane and/or useful? ;)
