Some interesting thoughts on copyright, creativity and technology in this TED Talk (you DO know about TED Talks, I hope).
P.S. I just found out that Larry Lessig will be one of the speakers at the TEDx San Antonio event on October 16. You can apply to be a participant at the event at the web site. TEDx is an independently organized (ie open source) event patterned after the TED programs in California. For more information go to http://www.tedxsanantonio.com/
