No IP Addresses for RIAA

From ars technica:

The music industry's requests for more personal information regarding the identity of several accused file-sharers have been shot down by a federal judge. Judge Nancy Gertner quashed a subpoena this week in the infamous London-Sire v. Does 1-4 case, saying that the IP addresses of three anonymous Boston University students could not be handed over because the university had "adequately demonstrated that it is not able to identify the alleged infringers with a reasonable degree of technical certainty."
