Re: Stego for watermarking Perl5 code?

Shabbir,

In the 70's and early 80's, I was part of a team distributing
a modestly massive Fortran program that we wanted people to
use but not commercialize.  Our solution then, well before we
all got so smart, was to convert every label, variable, subroutine
name, etc., to a random sequence of M, W and N, all six characters
long (3^^6=729) and that seemed to derail the modifiers.  We did,
for what it is worth, hide a customer identifier in there somewhere.

Low tech, but it seemed to work.
