    Also, regarding the recent conversations about text messaging and cheating on tests, there are cell phone neutralizers as well. They are or will soon be in theaters, restaurants, etc.

    I know a few professors put cell-phone jammers in their lecture halls to just flat out stop the use of cell phones during lectures and tests.

    "It could also be used in business settings—for instance, to stop amateur photography where shopping-mall-Santa pictures are being taken." :grumpy:

    This "technology" can be defeated with a new type of camera lens: 1) first lens projects image onto translucent screen; 2) second lens focuses screen image onto CCD. :tongue2:
