just a point on that RF-IR bug an arduino board+xbee shield+a experimental IR shield we where working some time ago (finally released but we have done some prototype) I bet it can work as Werner suggested .. just have to implemente xbee protocol stack on Ben or implement the whatever protocol Ben use on Arduino :P
