Gidari quoted at length in Ecommerce Times article on data retention for ISPs

Proposed legislation that would mandate storage of IP address and other information by ISPs may aid law enforcement but would open up ISPs to more civil discovery demands by those seeking to enforce intellectual property rights like the music industry or even in divorce cases when a spouse seeks to show the viewing habits of the other spouse. ISPs also have their own interest in using the data for advertising and network monitoring purposes. Gidari discussed the history of the laws that give ISPs broad rights to use the data, and the privacy risks associated with those uses.
