And since we see where the star was 10 years ago, you'd have to aim
the beam to where it will be, along the curve of the universe, 20 years
from where you see it now.

But then again, brute-force cracking the RC5 algorithm is pretty
useless, too, since noone who *really* wants to crack the cypher
will use brute force, but will use custome hardware, and smash it
in a fraction of the time...

Anyone know of gene analysis or protein folding, where the results
will be put in the public domain?
