"See-through" lenses

Have a look at the link below:

IR Pass Filters & Infrared Lens for Sony NightShot. Panasonic NightView KAYA Lens

KAYA optics have developed Infrared lenses which can see-through objects. The images from their experiments show how they can see through clothing. Not only that, the 2nd experiment, amazed me. Permanent ink is spilt on a document. The text in the ink spilt area is impossible to read then. But using this lens, the writing is clearly legible through the ink.

I wonder what will happen if such lens are introduced in the market.
