The firmware works with NEC, SHARP, SONY, SANYO and a variety of other IR code formats. Can turn ON or OFF the NUC, cost just ~$22 (Teensy, IR receiver, some wires and a micro USB plug ), no drivers needed under Win7 or greater (pre-Win7 requires a small MS driver). Here are some pictures:
Connecting these two connections (sticking a wire in the two holes) for a quick ~1/2 second count puts the Teensy in program mode.
Like to make my project open source, just don't have time to do all the leg work. I was surprised that a one device solution didn't exist to run on/off a PC via a standard TV remote control.
cool solution. providing a firmware/framework would be great!
though basic functionality is probably pretty easy to implement, it would be nice to have this as a maintainable project!
i do have a question (that i think i know the answer to). why are you using the usb data lines (or require a driver pre-win7)?
i suspect it is to allow you to program it without using another machine (thus having your environment always installed on the host itself)?
ive used these in the past for augmenting devices with ir power on:

these are a little cheaper to replicate, but perhaps not as flexible (depending on your needs for reprogramming (true ISP!
))
i would like to augment or build a design that incorporated a line-level (hard-wired) IR hand off (2.5/3.mm mono/mini-ts cable) for use with IR distribution or RF->IR bridges that commonly use this interface. using hardwired IR is really nice.
my current method of doing this is to add and wire a jack to the end of an internally located IR blaster positioned to hit the existing sensor (or one ive added).
this allows me to not have messy blaster wires and flashers stuck to the front of all of my devices. instead i have a clean cable that is easily removed from the rear of the unit. it also increases/ensures reliable IR signalling and can helps with issues where line of site or interference are a problem. no more worrying about the secure adhesion of the blaster, either.
