NASA Open Source Agreement v1.3

[Tzeng, Nigel H.]

Jeremy,

The largest obstacle to contributions at the moment, at least respect to
WorldWind, is that the Java repositories are closed and the .NET
repository mostly dead.

The community could maintain an external repository that shadows the
nightly drops but thus far there hasn't been enough interest to do so.  If
someone did that, then it might be helpful...it could be as simple as
providing a script to automate SVN to GIT conversion every night as
opposed to generating the zip file they currently make.  There's a dead
version of this somewhere on github.

Rewording NOSA would make it less confusing and perhaps resolve any
incorrect perceptions but I don't think that it would materially change
the amount of community participation. :)  If that's your goal then a
really cool WWJ community project would be more effective unless you
really believe that no one is building a open source Google Earth program
on WWJ strictly because of NOSA.
