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. Cheers, -- jra
