In the mean time, I'm going to be developing a native format for meshes, skeletons, and animations. The primary goals of the format are efficiency and congruity, so it'll be a binary format mirroring the internal representation of the data in the engine. I've already completed loaders for mesh and skeleton formats. I also began writing a Blender exporter for the mesh format, but blender.org went down and stayed down all day so I haven't been able to access the API documentation. So far I'm finding the Blender/Python API to be very concise. I also wrote a transform script which flips between right-handed and left-handed coordinates.
Lastly, I stumbled upon Google's Summer of Code. You write code for an open source organization over the summer and google coughs up $5000 when you're done! Definitely something I'll be considering next summer. I would especially love to write some cool stuff for Blender.
