Why not issue a key which is some hash of the device serial number. The user enters it in once and the application stores it as a 'feature'. Each time the app runs, it checks for the presence of the key, and checks if it is valid against the devices serial number.
This way, the user only has to enter the key once every time the software is installed, this shouldn't make them too unhappy. The software can be copied, but won't run without a valid key. The only way this can be broken is if someone dissassembles your app, locates the hashing code and discovers your hashing algorithm.
