I agree--it looks like the controller functions are making enough diverse usage
of the request object itself that it is hard to find a good seam for this change
right now.

Apart from all that, this looks great to me. It very much accomplishes the goal that I can add a new controller with arbitrary requests and responses without having to shoe-horn them into the existing default xml serialization code.
