Brian,
That sounds like an excellent idea. Thank you.
Out of curiosity, why would I shape rather than police on the downstream
router?
Does it make a difference? Actually, my hunch is that either would work for
this purpose, do you agree?
Thanks, Tim

Tim,
You could do extended ping with a timeout of 0 and then shape
the outbound interface to your desired rate. This would have to be done
downstream of your QoS config you're trying to test.
