I agree with milkshakes on this one. Brazzy...you are right. CDNs (in their current form) don't scale well. A properly executed p2p CDN can scale much better,

I agree with milkshakes on this one. Brazzy...you are right. CDNs (in their current form) don't scale well. A properly executed p2p CDN can scale much better, IMHO. As for not including users themselves as middle men, I must disagree with that. It makes economic sense for the ISPs to want to convert bad p2p traffic to good p2p traffic. That's their goal...all the while monetizing that good p2p traffic. Put it this way, the ISPs will do nothing, except sign a revenue share agreement and possibly change their TOS to allow customers to resell their bandwidth. For every GB resold, the ISP makes money. So in essence, they are converting bad p2p traffic to good p2p traffic and making a killing - the economics works in their favor.
