Oh, okay that's great. How hard would it be to get openblas numpy
wheels up and running? Would they be compatible with the existing
scipy etc. binaries?

OpenBLAS is still pretty buggy compared to ATLAS (although performance in many cases seems to be on par); I don't think that will be well received for the official releases. We actually did discuss it as an alternative for Accelerate on OS X, but there was quite a bit of opposition.
