Albert reminded me that we could potentially tweak the buildbot to do
this packaging.  There are, however, two issues.

First, the buildbot currently only supports numpy.  Compiling multiple
projects (residing in different repositories) with buildbot isn't
straightforward, but with a bit of hacking it should be possible (the
source is Python, how hard can it be ;).

Second, those machines all have different configurations of ATLAS,
MKL, etc.

Another option is to build the packages under vmware.  If you can
obtain a licensed copy of windows somewhere, there are instructions on
the internet on how to create a vmware image.  Vmplayer is a free
download.
