BitTorrent's content delivery system, originally developed as an open-source product, uses a "peer-to-peer" downloading method that can piece together a file from several servers at once, as well as from the hard drive of every user who has previously downloaded the file, taking the bandwidth burden off any single source.
Kang pointed out that Genachowski was dealt a setback when a court decision last April supported Comcast's ability to manage a notorious file-sharing application called BitTorrent that was slowing down the system.
