Re: Controlling licensed software?

Take a look at Crypt::License on CPAN.  I used it a couple years back to do
exactly what you are trying to do.  It encrypts your Perl source code and then
decrypts it on the fly.  There is a slight overhead for the decryption, but if
running under mod_perl, that should be negligible since it would only need to
decrypt on apache startup.

Ironically, I set it up for a company who was trying to enforce payment by their
customers, and then the bastard didn't pay *ME* for part of my work. (I was an
independent contractor)

Anyway.. HTH,
