Jeff,
I got the apc powerchute daemon and xpowerchute to work on a single machine, although I am not sure how it would work on a network.
The only problem I had was figuring out how to run the X program remotely. Basically I installed enough of X to run a remote X term therough Winaxe from which I could run xpowerchute. The rest was fairly easy
Have a search through the forums for APC or UPS or similar and see the stuff I put up there about it. If you want any help, let me know and I'll do my best.
