I can't believe my first post is because of this stupid argument.
If the mole has something like go2mypc then it's trivial. I leave my computer on at work and control it from where ever I am. I could easily do everything from that IP if I wanted, and it would be impossible to detect my real location. I don't think this could be what he's using (he said he posted from a cab, and go2mypc is near useless without at least a laptop), but I'm sure similar technologies exist that could explain it.
Note that I'm not defending the mole. I'm defending the guy who said IP addresses are not definitive proof.
