Live Linux distro?
If you just want to try and watch dodgy streams of dodgy movies, why not just fire up Linux from a Live CD or a memory stick?
I am assuming that most malware won't find anything to infect.
Or are they just phishing for people who are too low tech to grasp the concept?
There should be a market for a "safe streamer" where you just load the CD/DVD or memory stick and torrent away.
I'm waiting for it to take off then releasing some fake "safe streamer" devices at budget prices.
