Renderosity galleries are not a PEER-TO-PEER file-sharing system, they are a CLIENT-SERVER file-serving system. Although Napster and KaZaA weren't made to be used to protect illegal file-sharing, guess what their main uses were/are? And I'm sure that you don't use KaZaA "because" of the spyware, but inspite of it. Spyware sends information about you through KaZaA to whomever (as the link mentions) is collecting the information; there is no opt-out button. I had Napster awhile back to "check out songs" only, many of which transformed into CD purchases (I own about 700 CDs). I also had a large stock of my own CDs as MP3s for my own listening pleasure - never made them available for download. I had my Metallica collection as MP3s on my harddrive, for my listening pleasure. Can you guess where this is going? I was banned from using Napster and threatened with possible lawsuit because I had Metallica MP3s from my purchased CDs on my system for my listening pleasure unavailable to anyone else. While peer-to-peer systems like this remain inherently flawed, I will avoid their use. Hey, if you use it for legal swapping, great, but you also have to live with the terabytes of swapped illegal files as well as possible viruses/trojans (why someone using KaZaA doesn't have a virus scanner is beyond me) and spyware. I didn't say "file-sharing is illegal" - please try to quote me on that. I said "file-sharing music, video, applications, etc." where it should be understood as copyrighten material not owned by the person distributing it. That should've been easily deduced. Sorry, KaZaA isn't a hammer, it's a child let out late at night to be with the his/her friends, not taking responsibility for any consequences of its own actions. Just like Napster, it is a facilitator of illegal or questionable behaviour, even if there is a benign usefulness to it. They tried forcing the responsibility onto Napster and where is it now?
