ITKid,
If it's anything like the compusa wireless keyboard I hacked, it shouldn't be too hard to place the pcb from the receiver inside the iopener, and run some wires from the ir receiver pads on the board to the hot-glued ir bulb at the front of the case.
You may have to remove the modem though, if you're planning to secure it to a standoff.
Have fun,
Kudzu :)
