XNA.BLEND is the result of my problems using blender to produce skinned models for XNA-based games. I found that using the .fbx- or the .x-exporter was not practicable enough.
After some weeks of experimenting different constellations i decided to build a custom importer to directly import .blend-files.
The current version works only with fully skinned (one texture material per mesh). keyframe-animations can be parsed and converted.
If there are files that break my importer feel free to contact me (ideally you send me a blender-file where i can reproduce the issue).
Donations would be appreciated to get further and extend the solution:
