Export laws don't just affect crypto

The recent posts about GPS made me research the state of the art of GPS receivers. Seems they are getting pretty good. Two pounds, sub-meter accuracy, attitude determination, all at altitudes up to 60,000 feet and speeds up to 1,000 nmph. But what really caught my eye was the fine print at the bottom of the spec sheet: "Higher altitude and velocities up to 25,000 nautical miles-per-hour options are available in the U.S." I gather from this that as long as you are in the US, you are welcome to use this technology for applications that require larger than 1,000 nmph speeds. Seems the software industry is not the only industry that's suffering from silly export control laws. --Lucky
