New anti-piracy initiative between UK ISPs and the music industry is supposed to have real claws. But somehow the threat of getting a good old fashioned letter in the post to re-educate you doesn't seem to be that threatening. What's more ISPs are falling over backwards to say what they won't do to back up those letters with strong evidence of real wrong-doing e.g. no spying on what their customers get up to. So some deterrent?
