So a little while back a big hub-bub started about being able to decoded DVD's. There is this and that, but since the code was open, there was a fight over trying to get it killed. Problem 1, the source code was published as part of the legal docs. Then it was defended by saying that code was protected under freedom of speech. This led to a whole slew of things that encoded the sourse in other mediums like song and in this haiku. I love this kind of stuff.
