The Blender Institute has just published their concept for a 'Blender Cloud' on the Blender wiki. The project aims to replace the current Blender e-shop business of 'selling plastic', and to offer file hosting, collaboration and asset sharing solution which is fully integrate with Blender. A first version for testing should be ready early February. You can follow the project on the Blender wiki and through its Blender Developer project.
