I would think that, if you had a lot of DSP work to do, it'd be cheaper
to do it with DSPs than with 486s.  Something like the TigerSHARC
card.  Doing matrix multiplies, vector math, or Fourier transforms is
likely to be a heck of a lot faster with DSPs than with x86s -- like a
factor of 10 for CPUs that cost the same amount.

A well designed system must take people into account.  . . .  It's hard to
build a system that provides strong authentication on top of systems that
can be penetrated by knowing someone's mother's maiden name.  -- Schneier
