I talked with a park ranger who had used a high-precision GPS 
system which decoded the selective availability encrypted 
signal. Access to the device was very tightly controlled and it 
had a control-meta-shift-whoopie which erased the key should the 
device be in danger of being captured. And this was a relatively 
low security device.
