The reason i'm asking is that there's no easy solution for IR control right now. You can either build your own receiver, buy a MCE remote of some sort or get a TIRA, UIRT2 or USB-UIRT. All three products seem to be mostly abandoned by their creators.
Perhaps the Duo is able to do this already? I have some old X10 IR Powermids and i know the transmitter sends an IR signal whenever the Tellstick transmits nexa codes. That method would only work until your neighbor buys one though, since there's no concept of house codes in the IR world.
It would be cool to have IR transmitter and receiver jacks straight on the hardware, even cooler if it could be integrated with LIRC so you could control XBMC or the likes without extra hardware.
As long as i'm dreaming, throw in a connector that you could loop back into the power button connector on the PC so the Duo could turn the PC on and off with IR or RF signals

Doesn't that sound tempting?
