I tried to find one for PS3, no luck.

And yeah, it's basically a computer that corrects all of the input problems associated with directly interfacing a keyboard and mouse with the 360. Before you would have a dead-zone, so you would have to move your mouse quite a lot just to get the cursor to move, and then you would have sensitivity issues caused by joystick acceleration. XIM fixes all of this with its own firmware.

The PS3 equivalent is called the "Eagle Eye"
