You could implement an oauth-ish implementation. Basically, that would
mean:
- user has to register on-line and purchase the application
- at the first application run, user is redirected to web (using
webview for example) and is required to login
- application should send some information to the system (app version
or an ID that would change accordingly)
- system generates a unique ID and returns it to the application
- application is able to check if the key is valid

Cracking this kind of protection would be fairly simple, but on the
other hand, the solution is quite easy to implement.
