I hadn't been thinking there were other zones that might be subject to similar 
pressures.  That said, if the demand is larger than I have been thinking of, so

system is the technology and operational realities of bespoke tamperproof 
hardware is trickier than it looks.  A market of more than one will help 
support climbing up the learning curve.
