It's been a while since I posted anything here, so here's a short summary of important stuff
World Wind 1.3.4 has been released, and can be found at http://worldwind.arc.nasa.gov/download.html
KMLImporter v1.00 has been released, and has been included in World Wind 1.3.4, and therefore it is not available for download here. In fact it should automatically update itself (if you leave the feature enabled), so I should never have to 'release' it anymore.
The Free Earth Foundation is one of the mentoring organizations for Google's Summer of Code 2006. You can find the list of ideas, including my student-teacher interaction system, here.
The WorldWind forum has now been moved to http://forum.worldwindcentral.com/
