They can track a lot more than IP addresses, your browser can provide a lot of information, not just user-agent but installed fonts, plugin information and much more. There is enough to do a damn good job of identifying you even when your IP address changes. It is certainly simple to see if you are one user or two. -- Neil Bothwick Nymphomania-- an illness you hear about but never encounter.
