P2P Issue is Hairy

P2P users amount to only one percent of Comcast's users, but those users are consuming 50 percent of the company's bandwidth, according to George Ou, an editor at large at ZDNet and the former technical director at TechRepublic.

Some say the ultimate solution is "more bandwidth." The problem is, that doesn't really address P2P bandwidth consumption, which automatically will scale to devour the additional bandwidth as well, some point out.

The problem is figuring out whether or not P2P applications really do pose outsize network loads, and must therefore be managed to preserve quality of experience for the 99 percent of other users, or whether P2P constitutes a lawful application that shouldn't be subject to rate shaping.

It doesn't immediately appear clear that there is a single answer. Traffic shaping isn't blocking. And even outright blocking sometimes is socially desirable. Blocking of viruses and spam come to mind. But even voice networks are designed to block some traffic when peak loads occur. One has to re-dial. Traffic shaping is somewhat analogous to the means used to cope with voice congestion at peak hours.

And, unfortunately, "more bandwidth" isn't by itself a solution to P2P network loading, it wouldn't appear. At some point, market mechanisms will have to be applied. At some point, the business pricing model will be applied in the consumer space: you can use as much as you want; you just have to pay for the usage.
