With jeremy we are working on an export/import addon for blender.
The goal is to import/export assets really fast to other softwares like maya, max etc.
Exactly like GOZ/GOB but with more than one object and in OBJ, FBX and Alembic.
We have a first version for blender, a friend is working on the max version and another guy on the maya version.
Video in french for now
Example with the max script.
Tell us what do you think about that
