Any possibility of this ever being ported to the Xbox?

There is already a port of this emulator on the Nintendo Wii and progress seems to be going smoothly. One of the authors said in a youtube comment that they have gotten the emulator to reach playable speeds on their latest SVN.
The xbox has pretty much the same specs as the Wii so I'm guessing it could run the emu just as well. The touch screen isn't that big an issue, lots of games don't even use it. You could set up an analog stick to control a stylus pointer and click it in to press down on the screen.
Link to the Wii version if anyone's interested
