RE: [PATCH] Power control

Somewhat off topic, but has anyone modded a power strip so it's outlets
could be remotely controlled, or are you all using pre-purchased power
strips with serial interfaces?  The ones I've looked at are way too
expensive for home use....I'd like something I could use to remote-reboot my
systems with at home when I'm traveling, but it's not worth $1k or more.  :)

Yes, I'm using our fence scripts from our cluster product to do the work 
of talking to the different power strips.  Did you ever post your 
patches for inclusion?  I just want power control from conserver and to 
not have to maintain a patch going forward. :-)
