Adobe has released its Creative Suite Premium Plus from 2005 for free online
UPDATE: Adobe is now saying that it was never their intention to actually give away CS2. It was simply a fix for users who needed to reinstall their software using an activation server that's no longer active. You can see their response on the Adobe forums here. It's unclear what will happen with the software now, but after receiving such incredibly wide coverage, it's unlikely they'll just pull it down. Adobe has just gone and done something we'd never have expected them to do — released an old version of Creative Suite for free online, for general use. Unfortunately, due to the intense interest this has generated, the site has collapsed under the traffic load, but hopefully it'll right itself in the very near future.
