It is not arrays of PPros that we should be concerned about.  It is
arrays of custom designed and built chips that crack keys at many times
the rate of a PPro and for a fraction of the cost.

If you had designed a custom chip that cost 1/4 what a PPro does and
did 4 times as many kkeys, the amount of money spent on the 8192 CPU
machine could buy a system eight times as fast as our current
distributed computer.
