One slightly annoying but difficult to cheat method would be
to force the user to visit your web site and copy a
key calculated in response to a unique challenge from the program
each time it was run.

The challenge could have elements of client name, system time and a
random number built into it. I'd avoid having the program do it
automatically as it would seem a bit "big brother".
