We know there are lots of people which offered to help us with the development of BB for free and this would be a chance to prove that they meant business. They would get some kind of reward, surely, we're not robots
That's why we are considering outsourcing the app to the community and interested devs as a semi open source thing but the greatest obstacle, as has already been said, was code and data access. We don't want developers to be able to gain ingame advantage due to their work on the app.
The only possible solution I thought of so far would be a tight cooperation between the devs and us, where we'd need to build a platform which would give the devs the needed data for their work without giving too much away. It would be a slow and painful process but could be basically essential for the survival of the game in the long run.
I'm open to suggestions (if you don't mind me hijacking this thread) on how to do this, especially from people who have information on how this is kind of thing is usually done. I can also make this more official once we get the general idea on how to do this.
