I never got a 'round tuit: we have pretty reliable power and all 
important stuff is on journaled raids.

As I recall you can send powerfail either to a monitoring daemon 
(apcupsd?) or as snmp trap; with recent firmware you can also group 
upses to send the signal only when both of them lose power (with 2-psu 
machines connected to 2 upses on independent circuits). However, this is 
the opposite of what you want.

Their networked power strip lets you turn individual outlets on and off 
-- dunno if you can do it via snmp, though. I'm sure you can wrap 
telnet/expect or http/curl script into a plugin if it comes to that.
