[ Jim Clark, "Firewall China" ]
A: A lot of people think that's not possible. It's difficult to enforce, but it's certainly possible. A corporation has a so-called fire wall -- a single point of entry into the corporate net. You can have a country that has a single point of entry into its "country net." It's doable. All you need, though, is one breach of security, and there's a leak.
A fire wall is a filter -- it filters and doesn't let certain people come in. You can only come in if you have the right permission. So you could easily set that up so that it would filter out your objectionable material.
