Hardware QWERTY-to-DVORAK Conversion?

Tom asks: "I was once a Dvorak keyboard user but the fact that where ever I went I was forced me to go back to QWERT. IMHO the ultimate solution would be a small software independent hardware converter that acts between the keyboard and where you put in the motherboard. This solution would allow you to move to any computer and quickly use Dvorak without messing with software key remapping. I searched hard around the web and the only thing I found that was close to it was the Chameleon Keyboard Customizer also linked here (just scroll down a bit on this page) made by some company named Sirius Industries. Does anyone know where to get this converter or have any other hardware converters that they know exists? Or any type of schematic diagram that will let one build such a convert? Help is appreciated." The first link lists a number for Sirius Industries, but it was tied to a fax machine at the time of this writing. It would be nice to know if they are still in business and if there is any way of contacting them directly about their product.
