I think you should add to your "next steps" (4) some kind of remote server sync thing. eg. so you could have a database of all people and stats like how many washington plates were seen in total. As an example for the exercise, because it would seem that's a common use-case.
In fact, what I intend to experiment with is to use Facebook. In particular, something called Facebook Graph which is basically an API for storing and retrieving stuff. Facebook also solves the authentication problem with cloud storage solutions.
