Also interested in this especially for pathfinding/environment mapping. I assume you could theoretically play Animations and then move it around but that seems kind of "hacky" in a way, wish Reality Composer Pro had something like ragdoll support.
Using Unity with PolySpatial (when it becomes available) might be an option but I don't think you can integrate Windows with it.
