p.s. The fact that the sender of traffic should be paying some portion of the resulting costs is not a surprise to anyone; many of the content companies that I've spoken to believe they already are paying more as traffic increases, and were quite surprised to find that it doesn't actually make it to the networks which bear the brunt of the traffic carriage.
Why don't you just resort to a bit-counting method that I suggested earlier for settlement peering, and make the *SENDER* carry the traffic to the 'local' destination ? That way, the sender has to build a large enough network to distribute its traffic to the destination networks, without just presenting at one network point and expecting destination networks to foot the inter-state / inter-country traffic .. ?
