Certainly.  I'm putting it on my TODO list, because remote customers often
accidentally disconnect their UPS, and having something pingable *not* on 
the UPS would be a great backup.  I have no idea when I could get to it,
however.

You'd want failover functionality for the backup application.  I.e., if
the something is not pingable, BUT the regular UPS monitoring is
working (and the power is actually on), then do NOT initial shutdown.
The customer accidentally disconnected the something instead.
