But it is true that the former Warsaw Pact countries (and Russia) have primative versions of national "firewalls" for both data and voice that are similar to what the PRC are doing. I am WELL ACQUAINTED with this. So much so, that it makes for some interesting work - personal values conflicts. I am ashamed of the help that US high tech companies are giving to governments who do not believe in the free flow of information. My peers in this industry are doing the wrong thing and are letting "globalization" and "participation in emerging markets" blind them to doing what it right.
Have you taken a good look at RUNET (Russian Internet)? It's probably the most unregulated internet in existence.
