This sounds like a fantastic idea,
Connect the UPS to a PC. and have the PC signal the RaQ (Qubes)
to shutdown.

BTW I was able to get a PC (Linux Desktop) to work with an APC box
as outlined below. I just never could get it to work on a RaQ.

I think you need a gadget. There is a powerstrip with ethernet, and after
you tell the RaQ, Qube to shutdown you tell the powerstrip to remove power.

When I was messing around with this stuff a year or so ago, I was able to
shutdown the UPS, I would put the Linux PC in a shutdown state and the last
thing it did was check to insure that line power was still unavailable, and
then send a shutdown command to the UPS. The UPS shuts off after the RaQ
shutsdown everything.

When line power comes back on the UPS powers UP and so does the RaQ.
