In July I promised to track down the Blender exporter that was lost during the GotDotNet phase out. The last version of the export script is now hosted on CodePlex (here). I am embarrassed that it has taken me this long to do this, and even more so that the script is not up to date for the latest version of Blender.
This has forced me to admit that it's time to give someone else the opportunity to take ownership of this project. If you're interested, contact me.
