The Python bindings already have support for exactly this capability. The
ObjectTree class takes a base path, eg /org/foo/bar, and then handles
calls for any object below this point, eg /org/foo/bar/41254 without needing
any of the sub-objects to be explicitly registered - only the base path
is registered.
