Hi Steven.

Thanks for getting to us about it.

I would *think* that extending such a hack is the best way forward,
but I'm not 100% sure about it. Numpy also requires finishing and the
work has stalled recently (it's almost exclusively my fault, I have
been doing other stuff recently), but we're definitely looking forward
to implement a way of having scipy work one way or another.

Btw - I'm not aware, but how hard would it be to port scipy to pure
python & pure C with cffi in between?
