If part of application will run on this external device then it will be 
quite good protection. But if it will be used as sort of 'protection key' 
only then it will be breakable like it was with PC software which used 
hardware keys connected to parallel port. All what is needed is good 
cracker, legal copy and some time to analyze connection application<>key 
and software emulator of key will be created.
