Cool, cool, cool! You probably won't have any luck to use this with PyPy, because our ctypes implementation is extremely rudimentary (e.g. it imports and not much else). However, I hope to work on it a bit in the next weeks, so making the sqlite wrapper work is a nice first target.

I think our goal is to be as compatible to the ctypes one as possible. As I said above, I am not surprised that nothing works yet :-).
