Since the optical mouse is a miniature camera, the same type of principal could
be applied using the Lego Camera, maybe even with a custom template in VC. This
would at least be an "all lego" solution (for the purists out there). The focal
point could also be adjusted to give more ground clearance of the 'bot.
I believe the PS/2 port is serial based and requires a clock signal from the
"host". On that note, interfacing a PS/2 (and other serial devices) to an RCX
sensor port should be possible either through direct wiring or using a some form
of logic control (PIC) to handle handshaking.

One other interesting thing about this idea-- If it works, not only will
you get the optical sensor, but you can probably get up to 5 touch sensors
and a rotation sensor at the same time. I'm not sure how the signal is
sent, but will the RCX be able to differentiate between these on a single
port? Or, could you hook it up to two ports & set them up to work together?
