Lets say I want to log my visitors who are visiting my site and make it as accurate as possible. IP is out of the question because of dial up users so I'm interested in knowing if its possible to use another method like searching for a users MAC Address or some other system Identifer that changes little to non. Is this possible in PHP? How about JavaScript, I know JS can get a lot of information about the client but something that would identifer one box from another?
