writes "This Interactive Week article suggests that P2P is a wonderful thing, the direction the Internet is going ... and utterly breaks ISPs' business models, to the extent they may raise their monthly rates, or at least offer two-tier plans that will charge some users more. If true, ISPs might be seeing cost increases from two directions: more dialup ports (because users are staying on longer, so peak usage increases), and fatter pipes to their upstream or peer ISPs. On the other hand, to quote the article: "We're seeing greater decreases in the cost of the bandwidth than we are seeing increases in individual bandwidth usage." A price increase might or might not be justified, but Slashers will surely be interested if increases are coming."
People have been making this arguement for a while - remember when web surfing started to become common, and people stayed on for longer, the ISPs claimed the same things.
