Another method would be to require a log in and use of a system authorization (a computer ID) each time you used the dongle on a different computer. When you moved it back to another computer, you’d have to again log in and authorize. That way, if stolen it would be useless … so there would be no reason that a simple replacement policy wouldn’t be in order.
