An interesting snippet from the World Wind irc channel
expect that the api will be final and u guys can finally start doing stuff with it
(the api, not the core code)
the core code will be open source, but (as u guys like to call it) not open development. contributions can be submitted for review though
We were all kind of expecting this, but personally I think NASA is shooting itself in the foot. I know of quite a few very skilled coders waiting for World Wind Java to start contributing code, of course NASA is known for changing its policy so we can all hope they will reconsider, although I doubt this will happen while Tom Gaskins is running the project.
