yes, that was my idea when I proposed it.

I guess there is no chance to get pypy involved in such a project 
without using py.test :-).

I don't know Microsoft policies, it would be a real pity if that would 
not be possible because of vague legal issues.
But I think it would be possible to integrate it at least in fepy.

Moreover, having a working ctypes for all the four major python 
implementation would make it THE standard way to write extension 
modules, and the whole community would benefit from this.

yes, but then I'm not sure about performances. Still, a slower ctypes is 
much better than no ctypes :-).
