Thanks to everyone for the wake up!  I guess we all get lazy sometimes.

I settled with a 100k and 68nF filter with a 68k load resistor.  This gives
me a 0-2V window as required, and provides me with some hardware
safegaurds as well.

For my application the 8ms rise time from 15% to 85% duty cycle is
acceptable.  This configuration also gives me less than 50mVp-p of
ripple, which was my tightest spec. to meet.

Craig
