I would like to see OpenBLAS support for numpy on windows. The latest OpenBLAS windows builds numpy support for are on https://bitbucket.org/carlkl/mingw-w64-for-python/downloads now. Scipy wheels should work regardless if numpy was build with MSVC or with mingwpy. It is only mandantory to agree about the BLAS implemenation used.
