Building a Better P2P

The P4P Research Group, a coalition of most major ISPs, researchers and Pando networks, is working on a more efficient P2P protocol that saves transit time by only serving file parts from local peers to reduce hops. Pando and the new coalition believe they can speed up P2P transfers by as much as 235% across US cable networks and up to 898% across international broadband networks. In Verizon tests, Pando increased the percentage of data routed internally across their networks from 2.2% to 43.4%, which they claim reduced inter-ISP data transfers by an average of 34% (up to 43.8 % in the US and 75.1% internationally).
The project should get renewed attention this week as researchers from the
University of Washington and Yale University plan on releasing additional data
from project tests at a presentation late
today in Seattle. While the possibilities of the technology are
promising, there's a lot of questions concerning how this would be implemented.
Would ISP partners (AT&T, Verizon and Comcast are involved in testing) charge
customers more for prioritized P2P? Will the client source code be published?
Will the system come with anti-piracy provisions and if so, will it create an
ISP gatekeeper situation to wall off "non-sanctioned" P2P content?
