You can watch his lecture (Real Player req.) titled, "Rip, Mix, Burn, Sue: Technology, Politics, and the Fight to Control Digital Media"
The video is entertaining and informative, and well worth watching.
UPDATE (12/21): This post has been heavily edited. Prior to editing, I stated that Ed implicitly advocated the use of P2P technologies to infringe on copyrights. Upon receiving comments from both Prof. Felten and Prof. Solum, I realize that my statement was unduly harsh and intellectually lazy. I could, and should, have simply emailed Prof. Felten for his position on the matter instead of attributing any particular "implicit" view on his behalf. My apologies to Prof. Felten for any offense I may have caused and my apologies to Prof. Solum for lowering the level of discourse on this blog.
