I would have thought that they could track an IP address to a certain point and then maybe cross reference that with any accounts that are used for posting on blogs and stuff. So from that I would guess that a techie could make an educated guess. Although I doubt they'd be bothered.

Just the ability to receive a TV signal is what requires you to have a TV licence irrespective of what you watch on it, even if you only watch DVD's or games on it. I'm not sure if anyone has actually challenged that in a court of law.

Utlimately the BBC will do whatever they can to maximise their revenue. Although I'm sure it's all perfectly legal.
