Knowledge about TCP/IP is alot easier to control than knowledge about the Berlin Wall (ie, how many Chinese will even know of the existence of TCP/IP -- in the US, where this is freely available, how many citizens know of it's existence)?

I bet this would change if people saw knowledge of TCP/IP as the "key to the Berlin Wall."
