I/R and sonar is next after the sreaming video or webcam.

I just spent some time porting the code from Linux 2.4 to 2.6, I've also
done some work on the motor control loop. It is pretty stable and behaves
very well. I've done some benchmarking and am satisfied that the system
works well.
The mouse encoder system I built is using the PS/2 port. I am curious if
using USB will make it better. I don't know, there may be time slice
contention with the camera.
As for remote, I'm using Linux with wireless networking. It is inherently
"remote." Almost anything you can do on the console you can do over the
network.

I'm not sure I follow waht you are doing.

What kind of CPU are you using? Modern CPUs can do floating point just as
fast, if not faster, than integer arithmatic.
