Given that we are not going to keep the algorithm secret, could we just
tweak an existing standard [DES?] such that it renders existing hardware
solutions for that standard incompatible with our spiffy Canadian
version?  And if we do this, is the demand for Canadian secrets [how
much money does Wayne Gretzky make?] so low that no-one will bother to
design and implement hardware to crack such a 'tweaked' version?
