I'm passing on this article, it was a really interesting piece about a Wired writer who went off the grid/incognito for a month, with Wired magazine offering a $5000 bounty if anyone could locate him. It sounds easy, to disappear, and the writer took some extraordinary steps to be untraceable... at first. Then, he began to taunt the hunters--people all over the world took up the challenge to sniff him out through a myriad of IT tools and techniques.
So, it seems like this was a game, not a real serious attempt to be untraceable, which I would say is possible. Interesting story.
