James Cicconi, AT&T's senior vice president for external & legal affairs, set off a firestorm last week after The New York Times reported that he said his company was working with the Motion Picture Association of America and the Recording Industry Association of America to implement a digital-fingerprinting scheme and would detect and filter out copyrighted material from its network.

"Everyone who understands the technology agrees that most simple filtering efforts are doomed to fail, since all the file-sharing applications will simply encrypt the traffic, [thus] necessitating more complex deep-packet protocol analysis, at a minimum," says Fred von Lohmann, a senior staff attorney with the Electronic Frontier Foundation "I'm told that 20% of Bit Torrent traffic is already encrypted."
