Pam Samuelson, one of the world's foremost copyright scholars, is podcasting the lectures from her UC Berkeley Information Law and Policy course. Samuelson was one of the first people to criticize the DMCA, serves on the board of the Electronic Frontier Foundation, and has the respect of people from all sides of the copyright debate. I've learned something every time I've spoken to Pam. There's an RSS feed for the audio, too.
(Thanks, Mike!)
