Yeah, I like it.  According to the docs, this setup is still being tested,
but it seems to work.  Although it does assume (obviously) that all your
systems are on a UPS, otherwise, it wouldn't do any good to tell them to
shut down, since they'd be shut off from not being on the UPS.  So, if
that's the case, you can hook up all your systems to their own individual
UPSes and run separate apcupsds on each one.

I've personally got a BkPro 500 here.  You can get them for about 4 man at
Yodobashi Camera or Sofmap, in Shinjuku.
