Rip, Mix, Burn, Sue

Since it was only available in Windows format I didn't post on it yet: Ed Felten's lecture Rip, Mix, Burn, Sue: Technology, Politics, and the Fight to Control Digital Media. Now it's up at this page in several formats, and extending to more.
Felten concentrates on two issues: 1) the struggle for control over technology and the struggle for control how consumers are allowed to use recorded media and 2) the role of multi-use technology , technologies that have both legal and illegal uses.
I'm listening to it in audio, but Felten is making some PowerPoint jokes and has some explanatory graphics, so a video stream might be more useful.
