Does rate-limiting work like that?  I thought that if the condition is met
(i.e. the address is within the range specified in the ACL), the amount of
bandwidth specified in the statement will be given on a case-by-case basis. 
Or does it truly divide the bandwidth amongst all who are allowed by the ACL?

We once tried to simulate the throughput of a DS3 by creating a policy for
rate-limiting on a 100 Mbps ethernet.  Unfortunately, the machine running
ttcp to generate the dummy traffic couldn't sustain 45 Mbps.  I think they
ultimately went with two machines, which resulted in more than 45 Mbps of
traffic but less than 90 Mbps.  I seem to recall that the policy ended up
allowing *each* machine up to 45 Mbps - but I could be wrong. 
Unfortunately, the engineer responsible for that experiment has left for
greener pastures.

Anyone refresh my memory?
