BPI teams up with Virgin

This story has been all over the news sites lately. Virgin have agreed to monitor their subscribers' file-sharing habits on behalf of the BPI. You can read the exact details for yourself, but what I'm interested in is exactly how they are going to do this - keyword filters, digital fingerprinting? Is there a risk that users might get a strike for legitimate uses of file-sharing technologies? As we see more and more Music 2.0 we're likely to see more and more bands distributing their works via BitTorrent, are users downloading a new Nine Inch Nails album at risk of being targetted? Will we see a repeat of the recent blunders of (RIAA lapdogs) MediaDefender and seeing legitimate 'traders' suffer denial of service attacks, disconnection or the indignity of having a black mark against their name?

Quite frankly I'm disgusted that Virgin have bought into this.
