What I'd really love to see with this is some kind of monetization model outside of just relying on sponsors to a non-profit. Although I'm not a huge fan of their specific license, I think maybe the FUTO model might be something to look at: The user is fully free to inspect, modify, and redistribute copies of or modifications of the source code of the application, and the full features of the application are available at all times to all users, but there is a way to "pay for the application if you like it" built into the interface that is easy to access and convenient to use, that gives people some kind of "lifetime license" that just adds a rewarding cosmetic thing to their account or something. Maybe with a one-time notification reminding the user to pay after a certain amount of time using the application that can be permanently dismissed with a button that's part of the notification.
