Kuhn's paper (400k PDF) is available.

    The real danger here, I think, isn't some kind of "national security" or "bank fraud" or anything like that -- security schmecurity. The real danger, is Quake cheating!

    Think about it. If I can reconstruct what is on your monitor, I can tell where you are. Are you down the tunnel? In the water? Are you on top of that goddamnfucking sniper tower? I could reconstruct your screen and determine exactly where you are in the Quake map.

    Quick, someone, solve this problem before it tears society apart!!

    Now I can begin selling my high-tech, computer privacy protection devices.

    I will call them curtains.

      But with the LCD, we won't have the dastardly spy saying:

      "Curtains, foiled again!"

      OK, that was bad. Forgive me. :-)

    Now I can justify the 21 LCD at work on the grounds that the CRT poses a risk of industrial espionage.
