I had forgotten that thread, thanks for reminding me. I guess my idea
arose from my forgotten memory of that thread , but I was thinking
that it may be less of a burden, and allow more sharing of work, if we
concentrate on testing. For example, if we have a testing repo on the
OpenBLAS org, I can imagine Julia / R developers finding bugs, and
adding tests to the Python repo, because the machinery to do that is
already built and documented (in my perfect world).

I'm afraid I'm not going to Scipy this year. Nathaniel - would you
consider organizing something like this, with able help from those of
us going and not going who can contribute some time?

I can well imagine that BLIS will be a good option at some point, but
I'm guessing that it is unlikely we will be able to to use BLIS for
our default BLAS / LAPACK library on Linux / Windows / Mac in the near
future. Is that right?
Cheers,
Matthew
