Personally I'm just waiting for the C++/DirectX model to be supported. It makes more sense, because AdDuplex is IMHO best for indie game devs as a hardcoded fall-back position for Microsoft's own advertising platform (which can frequently fail to serve ads, for whatever reason).
C'mon, HN, you can do better than this!
