You know what would make this work *well*? If IAPs *didn't include mcast
traffic in your cap*. Since the reason for their caps is, in the final
analysis *to limit THEIR transit costs*, multicast would seem to be a
really good means toward that end, unless my final analysis is contradicted
by something better justified and documented...
This would turn multicast into a Consumer-pull technology.
