Looking at possibilities for an implementation of usage-based

I'm looking for some feedback from the list on experiences with these
tools and techniques as well as alternatives that may not be listed
here.
+Techniques
--Flow data (Netflow, SFlow, etc) analysis to
determine 95th percentile traffic levels
--SNMP polling of interface counters to determine 95th
percentile traffic levels
I need to look into this in the near future as well. The problems I'm
aware of are:
1) we have customers on policed ports, and the interface snmp counters
count packets before service-policy. It doesn't seem right to bill
for packets we dropped :)...so this isn't useful data for billing
purposes.
Torrus (www.torrus.org) can use the Cisco MIBs to graph pre and
post-policy packets.
