>What kind of traffic inspection are these ISPs doing that would enable to identify infringement as it's happening? As I understand it, there's no actual monitoring being done by ISPs. The monitoring is done by the record and movie companies. When they see a torrent of their content being shared, they record the IP addresses of everyone seeding that torrent and then send warning requests to the ISPs whose users are uploading. Those IPs then relay that warning to the actual users associated with those IPs. Once a user gets six of these warnings, the ISP is obligated to cut off the user. At least, that's the way it was reported last summer, and that's how Ars Technica is describing the enforcement system now.
