6500 with Sup2/PFC2 *cannot* do policing/shaping on outgoing traffic in
hardware - you need the Sup720 (or -3BXL) for that. Sup2/PFC2 does fine
with incoming traffic.

You should still be able to do it in software (good old fashioned CAR),
though I never tried that. Will obviously increase your processor load.
