Did anyone read the link I posted? :|
It was decided in Nevada that because of the ability to 'protect' content from google with a robots.txt, that the cacheing of content constituted 'fair use', and wasn't in breach of copyright.
Now I realise that Nevada law isn't going to automatically influence the law everywhere else, but it certainly means it isn't as clear cut as it seems Nodrog would have us believe, and that (in some contexts at least) it seems the onus is on the owners to tell search engines to skip over their content.
