Scipy for .NET looks like a dream come true to me. MSVS roundhouse kicks every other python IDE in the face, and seemless interop with all other .NET languages would be awesome (looking at you in particular, F#... you could really be the functional gateway drug... but I can't leave my scientific python toolstack behind!)
Very sad to see that it appears the project is not very actively supported, to put it mildly. First thing on my todo list if I win the lottery... Supporting this project would be a staggering reward/efford project for Microsoft to boost its standing in the scientific computing sphere; going from being almost entirely of the radar, to the very top of the stack. Just in case anyone with a budget at Microsoft is looking at this: seriously. You are already giving MSVS for free to this crummy academic anyway, but I'd force my future boss to buy my MSVS at gunpoint*, if you realized the full potential of this. (*not that my amazing productivity wouldn't convince him anyway...)
So no, not much of a direct answer to your question, but maybe this rant will pay off sometime in the future.
