Re: Just content providers trying to shift costs to ISPs

P2P is fully scalable
Only if you ignore reality.

P2P is still a minority application on the Internet and it's still driving traffic only 2nd to HTTP. Since HTTP is a universally used application, that's saying quite a bit.

P2P video distribution will fold existing networks before it reaches any kind of truly meaningful scale, because we haven't invented high enough capacity hardware yet to be able to replace video distribution with a jumbled mess of unicast feed.

A film can become an overnight hit and have enough seeds to stream it. Can your server farm do that?
Akamai cracked this nut a decade ago. P2P distribution is a half-ass approach to the same problem that shifts the distribution load to the edge of the network where links are slower and infrastructure is more expensive. Either way, having overall bandwidth consumption increase linearly with every view of identical content is strategically retarded.
