Back in 2004 when we worked with Technokats to rework an optical mouse to detect robot movement, we interfaced directly into the chip in the optical mouse and bit-banged the protocol. It was pretty easy with the IFI RC. At that time, there was only 1 manufacturer of the optical interface chips (probably due to patents etc). Not sure if that has changed since then.
