or may be Great Firewall does it right :) Btw, can NSA splitters function as such as well? Or [selectively] replace real traffic with artificially generated one? (I mean pure splitter wouldn't, yet why it would be just a pure splitter? why limit themselves to read-only capabilities only? May sound like a new tin foil hat frontier for some ... yet i think we do need one at least as a guide post into the future as the reality has already moved well past the previous one)
