Right now it is a very cool laboratory experiment. Probably 10 years from a commercial product. The image processing required takes gobs of processing power and the programming language that could describe the variability of real-world situations probably doesn't exist yet.

Kindof like the holographic data storage that I've been hearing about for 10 years... (wiki HVD)... 10 TB on one disc.

Dream about the future, but not at the expense of today.

Remember, your grandma pushed a hoop with a stick. A stick!!!
