There's an article in Computer World about Big Think, a website that is a sort of YouTube for serious intellectuals (motto: "We are what you think"). Big Think is still in beta but is already offering over 100 hours of video interviews with leading thinkers, movers and shakers. You can search the videos and - here's the main point of the site - respond to them with your own video, audio, comments and ideas (registration is required but free and easy).
You can browse the videos by category - in the category of law, for example, the videos include Alan Dershowitz on "How did we develop legal systems?", Justice Stephen Breyer on "Does globalization pose new challenges for the Supreme Court?" and Yale Law professor Stephen Carter on "What are the great issues facing the legal system today?"
