Well, what would you call a network processor? An FPGA or a CPU? I think of
it as somewhere in between, given credence to the FPGA statement below.

Indeed so. however, the argument in 1998, a FPGA machine broke a DES
key in 72 hours, therefore TODAY... assumes that (a) the problems are
comparable, and (b) that moores law has been applied to FPGAs
