What you're refering to is known as a dongle and I would guess that there will be some sort of challenge-response mechanism involved which may require a fair bit of reverse engineering, you may as well just use the dongle. If you want to use it in a computer that doesn't have a parallel port you should be able to get hold of a PCI IO card with parallel ports on pretty cheaply.
