Looking at possibilities for an implementation of usage-based billing, it seems that the same techniques and tools always come up. 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.

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. http://www.torrus.org/plugins/tp-cisco-cbqos.pod.html Sam
