Looking on the internet, it looks like Sony can tie an IP to a consoles serial number/MAC, but requires police involvement to do so. And that would be down to if the police felt it was worth the time. Plus this is 'the internet' saying this, without any official confirmation of this it could all just be bull.
Lot of ifs, buts and maybes, but certainly worth finding out I would think.
