I have an idea for an open source app -- the app would be free, but I would charge a small fee for data that a customer would order. For instance, let's say I'm writing a map application. I'd give the app away, make it open-source, but I would like to sell various maps to individual users.

Is there a way to protect the data in such a way that makes it very difficult for someone to simply take the map they bought and distribute it to others? Is this feasible for an open source app?
