Yeah, I even have an article there, but it's way outdated. I guess it's up to us to fix it, though. I'll check out what works for Blender and do something. I'm pretty sure the geometry can be done by exporting to FBX and then using the FBX converter from autodesk, 2011, to convert to 3DS. Unfortunately they dropped 3ds on their most recent converter, but they archive the older copies. There's probably some point in time where Blender's .x exporter and 2011 FBX converter sink up and the GUI hasn't changed much since then.
