[comp.sys.mac] software locks

Are there any Macintosh-based software locks?  These are devices you can attach
to a serial or parallel port that have unique identification registers that a
software package can query before running.  This allows a user to backup
software while preventing unauthorized copying.  Several companies market these
devices in the PC marketplace, but I need to know if they are available in the
Macintosh marketplace.
