10F320/2 looks really good.  Only thing I'm wondering is that it seems=20
the PWM voltage output is based on the supply voltage, so for higher=20
accuracy, should I run the analog output back into an A/D for some type=20
of dynamic closed-loop adjustment?  If so, I'd go for something with=20
 >8-bit A/D.

Alternatively, I could monitor the power-supply voltage and adjust the=20
PWM value accordingly.  But here too a 10-bit A/D would be nice.

The 12F1501 looks promising.

Cheers,
-Neil.
