Are they sure they can differentiate between "illegal sharing" and the likes of the BBCiPlayer, ITV`s thing, Sky`s... iTunes stuff..
Afaik, just to take the iPlayer as an example, if I download a solid weeks worth of shows and watch them with deletion, those files are open for p2p access, as is how the system works.
Is this just a smoke screen for identifying plainly high bandwidth users and stopping them ? Using a threatening stance, covered by legalitees. - whilst at the same time the ISPs attempt to save face with the simple answer - "we were against this, so don`t blame us".
