Or no one is getting paid full time. That might be a good thing for a project like this. A full time employee might bring with it some perverse incentives (if it reaches a state where the community isn't clamoring for a full year's worth an an engineer's time, what happens to that engineer when the work is gone, or what if they find things that aren't needed to justify more work?)

If their current balance is over two years worth of their annual budget and the users are happy with the project and how its progressing, I'm happy to think they're in a good place until I hear evidence to convince me otherwise.
