John Perry Barlow is an interesting guy. Wrote songs for the Dead, now is a pundit on the whole arena of intellectual property. He sees modern copyright law as stifling the sharing which has been a key underpinning of civilization and its advancement.
Something that may help is Stanford Professor Lawrence Lessig's upcoming launch of Creative Commons. I don't know enough about the details to judge whether or not it's workable, but it sounds like a huge improvement over the current situation, in which you have music labels and movie studios spending millions of dollars litigating to maintain their right to overcharge for CDs.
