I use MySQl for copy protection because my apps are internet related.
Still need the hard drive serial number thou to decide if a computer that
is loging in is a different (and disallowed) computer than the one already
logged in or if it is the same computer relogging in becasue of conection
loss, crash or power loss.
This methord of copyprotection I find is very hard to hack and if it is
hacked it is easy to spot.
No good without the required connection thou.
