This is an important point - how to handle the concurrency, effectively we'd need to have parts of the scene graph cloned by the rendering scene graph and the physics scene graph, the rendering scene graph pulling values from the physics scene graph. The physics scene graph may well be identical, but have a thread just working on different elements that the rendering thread doesn't modify - such as a cached matrices or meshes.
