Linking the printed page with the digital realm via cameraphone

In the "freaky future" column today is a technology announced recently by Fujitsu that can encode data into an actual image that the human eye cannot see — but can be decoded by a cellphone with a built-in camera (which includes almost all handsets these days.) This "hiding in plain sight" technology probably has implications for the publishing industry above all else as its way of linking analog (the printed page) into digital (the searchable digital image). Pretty nifty swank going on there, Fujitsu. Can you mod this to remove those nasty serial numbers from our color laser printers? If ya find the time, we'd appreciate it.
