Actually yes, yes I do.

The linuxpcrobot (www.linuxpcrobot.org) :-) currently uses a PS/2 ball 
mouse for the motor encoding system. Since PS/2 ball mice are about as 
common as your run of the mill dodo bird, anyone trying to build the 
thing is pretty SOL when trying to build their own.

Also, I use a K8055 I/O board to do some fairly simple D/A for the motor 
drive system as well as A/D to read battery voltage.  The PWM motor 
drive system takes +/- 5V analog drive signal. +5 forward, -5 reverse 0 
volts stop, and produces PWM.

There's no reason I can't use the two CTC  to do the PWM, use a couple 
bits for direction, read the motor encoders, and monitor the battery 
voltage in the Arduino. If there is enough headroom, I may even move a 
little more of the control functionality in.
