One thing I don't understand is why Google felt the need to comply with the Kazaa demands - after all, it's not as if Google was caching illegally copied work stored on an unauthorised third party's website. It was just pointing its users towards sites which offered ripped off copies of the Kazaa client. This, of course, is similar to what Kazaa's software does itself when it shows you the way to an illegally-copied MP3 music file.
I've been trying to find out more from the rather excellent Chillingeffects.org website, which "encourages respect for intellectual property law, while frowning on its misuse to 'chill' legitimate activity".
The site is well worth a look around by itself: any organisation which describes an aspect of US copyright law thus: "For instance, if I perform a Klingon death wail in a local park, my performance is not copyrightable. However, if I film the performance, then the film is copyrightable" gets my vote... They have also provided a list of the sites removed from Google - follow the link above, or type "Kazaa" into Google and follow the link at the foot of the first page of results.
