That's insane - "The Great Firewall of China the UK" implemented under the ruse of protecting rights-holders.
I don't know why nobody has pointed out to UK Gov that this whole exercise is a waste of time. As slackers says below there are plenty of ways round this.
For $5 p/month you can subscribe to a commercial darknet based in a country where the UK will have no legal resource. You can then effectively do what you want.
And anyway such legislation will just drive the further development and uptake of trackerless bittorrent (and similar) technologies.
