Yesterday watching Modern Marvels, there was mention about the next generation Firewall, which involves using Quantum Physics (SPD, I do believe this is right up your Alley). From the sounds of it, is a neat way of stopping hackers, but cost analysis, is it actually going to be cheaper?

September 30, 2004 (Computerworld) -- In theory and in labs, quantum cryptography -- cryptography based on the laws of physics rather than traditional, computational difficulty -- has been around for years. Advancements in science and in the world's telecommunications infrastructure, however, have led to the commercialization of this technology and its practical application in industries where high-value assets must be secure.
Protecting information today usually involves the use of a cryptographic protocol where sensitive information is encrypted into a form that would be unreadable by anyone without a "key." For this system to work effectively, the key must be absolutely random and kept secret from everyone except the communicating parties. It must also be refreshed regularly to keep the communications channel safe. The challenge resides in the techniques used for the encryption and distribution of this key to its intended parties to avoid any interception of the key or any eavesdropping by a third party.

I threw out the map a long time ago. Now I go my own direction!
