Did you follow what happened in the music industry? Someone wrote a piece of sofware that can decode copy protected DVDs, called DeCSS The MPAA (Movie Picture Association of America) in return threatened to sue, not only the maintainer of that site, but also everybody who would link to it. So, this guy wrote a piece of Software that’s called DeCSS as well, but totally unrelated to the “real” DeCSS. The idea is to make it difficult for the MPAA to find links to DeCSS, by putting this sofware out. Have fun!
