It's my understanding, could be wrong though, that there are system cookies that don't attach to the files on the hard drive but are actually on the BIOS and that no matter where they go or IP addresses used (changed) the specific computer can be located within a minute by pinging it. Kind of like the little I-Net phone adapters that no matter the number the companies still can find out where it's located.

I was speaking to a friend that got back from Afghanistan and he told me that a lot of senior military people believe that there are some reporters at Al-Jazeera that they suspect not only knew where the terrorist were but were actively involved in the murders for the news stories and that is how they get the tapes and Internet messages so easily without being detected.
