But... but... how do we count the viewers, then?
Isn't the real problem with global multicast: "How do we ultimately bill the broadcaster for all that traffic amplification that happened *inside* every other AS?" It seems like you'd have to do per-packet accounting at every router, and coordinate billing/reporting amongst all providers that saw those packets.
See, now, I expected to hear that objection.
Internet engineers are prone to try to solve this problem in favor of the viewer, and their networks -- with their networks winning in case of a push.
Should be easy enough on your subscriber ports to use igmp to see who has subscribed to which groups, shouldn't it? Just log igmp changes and there's your accounting.
