As I understood the initial description and examples, the ufunc overload will keep being used as long as its arguments are of classes that declare ufunc overrides (i.e., classes with the "_numpy_ufunc_" attribute). Thus Mark's comment saying that you have to either transform the arguments into raw ndarrays (either by creating new ones or passing a view) or use the "subok = False" kwarg parameter to break a possible overloading loop.
