AT&T Embraces BitTorrent, May Consider Usage-Based Pricing | Epicenter from Wired.com

AT&T will begin testing usage-based pricing starting this Fall. That’s driven by the economics of building network capacity, he says, not by an attempt to make more money. According to Donovan, one percent of the company’s customers account for 20 percent of the network usage; the top five percent account for 40 percent of the usage. Because the network must be able to accommodate peak traffic loads, AT&T — like other network providers — finds itself building far more capacity than most users need, just support the most prolific users.
