I have an ur-example of one of the problems with copyright law as it stands.
You know the works of Sarte? Like, in particular, the culturally relevant plays, such as 'No Exit'? Well, guess what, it's still under copyright. It was written just after the Nazis left Paris, and it's covered by copyright law. Sarte is sipping coffee with Socrates (who isn't drinking anything, bad memories doncha know) right now, and somebody is collecting royalties on his works.
Damn you, Micky.
