Specifically NO built in UPS, but perhaps a way to read the serial/usb/ethernet outputs of various ups manufacturers* and perform certain functions such as shutting down desktops# attached to the same ups, turning off or limiting power hungry functions such as wifi, and maybe a few other options. It should also be possible to trigger a user created script, for power users to do fancier things.
(*are these things standardized these days?)
#I'm not sure what means currently exist for doing this, but they're planning to make the firmware so if no easy native solutions exist I suggest making a service for windows/mac/unix that accepts a command on a specified port, then the signal can just be multicast. The service should be kept as simple and trim as possible, with only the options to shutdown or run a program. Users who want more can set that program to whatever they want.
