I am just waiting (and I am 100% sure it will happen sooner than you think) until you let your government read all your mail and listen to every phonecall. Hell, why not just install a GPS + camera + microphone chip on everyone? You Brits think that you live in a free country, but believe me, we have much more freedom here, in post-soviet land. You never had your freedom taken away from you, so you don't even know how much it is worth. We had the same thing - police listening to phonecalls, reading mail, arresting people over saying something "unlawful". Hell, we had a lot of it, first from Germans, then from Soviets, took us many, many years to get back what was ours, so we know how hard it is to get your freedom back once you gave it away. And basically this is where you are going, giving away all your freedom piece by piece. This system is not going to catch anyone. Come on, filtering on port 80? Any website that has something very illegal to sell (take UnderMarket for example) simply uses another port, mostly from somewhere up of the scale, like 55555. But this has another great potential - anyone ever been to China? Try googling "free tibet" there. I actually did it in a hotel, this made the following week the worst time in my life. Think, Brits, think. Use your own minds instead offloading all the thinking to government or you will end up as another China. And this is not just "bad sci-fi", this is exactly where you are going.
