Unique code for local machine

[pnoeric]

I'm licensing a piece of code to a company and I want to lock it up as much as possible. I'm going to use PHP Encoder to encode it so they can't get into my scripts, but I'm also wondering if there's some kind of unique identifier for the server that I install the code on, so if it's move to a different server (domain name?) it would stop working.

Any ideas? I could just go on the domain name that the script runs under... just wondering if there's any ideas from y'all clever folk...

best
Eric

try this on for size.... notice :
SERVER_NAME, SERVER_ADDR, and SERVER_PORT

i think these are what you are looking for

<?php

header('Content-type: text/plain');

print_r($_SERVER);

?>
