I use the drive serial number and don't spend any time administrating. I
allow a certain number of unlocks from different drive numbers and after
that the account is deactivated.

That is true, I got around that by writing an encrypted file when the file
is unlocked successfully. Whenever the game starts it checks to make sure
the game is still on the same drive. If not it prompts the user to unlock

That is a cool idea! :)
