Over here, in the European Union, where some countries (France) appear to be trying to do this, I've just read that the European Parliament has banned it. It will not be legal to ban people from the Internet. They say that this is akin to forcing people to be technology illiterates and cite several other reasons.
I've read this on several local online news sites but haven't been able to find an official link. If anyone does find it, I'd appreciate it.
