The Pando- and Verizon-backed P4P approach to optimizing P2P traffic for ISPs and downloaders alike might be a big hit with some access providers, but many file sharers are still skeptical.

Maybe this will change once the Internet Engineering Task Force, or short IETF, is going to get involved with these efforts. P4P proponents are planing to make their case at the 72nd IETF Meeting in Dublin at the end of July, with two so-called "Birds of a feather" meet-ups being scheduled to address Techniques for Advanced Networking Applications and Application-Layer Traffic Optimization.

The idea to get the IETF involved is not new. Pando CTO Laird Popkin told me a few months back that the IETF could be a good non-profit to run the iTracker servers in a P4P environment to make sure that privacy concerns are addressed. The draft statements written for the IETF meeting also go out of their way to address any concerns that P4P-like technology could be used to control file sharing. From the ALTO draft:

"However, ALTO is completely optional for P2P applications and its purpose is to help improve performance of such applications. If, for some reason, it fails to achieve this purpose, it would simply fail to gain popularity and would not be used.

Even in cases where the ALTO service provider would decide to maliciously alter results returned by queries only after the solution has gained popularity (i.e. it behaves for a while to become popular and then starts misbehaving), it would be fairly easy for P2P application maintainers and users to revert to solutions that are not using it."
