so you don't want accounts. a little daemon that you can telnet that would
initiate a shutdown would work **if** you make damn sure it only listens
on the internal interface. It should be pretty trivial to write in
perl (suid of course). If you are interested and nee dhelp, I'll see if I
can find time to try something this weekend.
As far as the status goes, worst case just wait a few minutes after you
cannot ping it anymore. If you get a smart UPS, you might be ablt to tell
the UPS to turn off.
