“In order to download (or upload) files on any peer-to-peer network whatsoever, all on-campus users have to pass an online quiz on copyright infringement. But not just once. Passing the test — with a perfect score — enables peer-to-peer access for six hours on the user’s on-campus registered machines. The next time, the student, staff or faculty member has to go to the intranet Web page and take the randomized test again.”
