Gosh. I haven't thought about GEB for decades, but I don't think you need to
restrict it to primes. I just need MY unique number (and the cool thing is
that I can retire, because knowing that, and having that rendering engine, I
can render the future as well as the past.)  Let's see... World population
of a few billion, maybe add a few bits for redundancy/ECC.. Everyone needs a
40 bit or so number.  Hmmm... Maybe that's why DES has 56 bit keys?
Everyone has their personal DES key. Or is there some more mystical reason..
I must go find my copies of Umberto Eco..
