Hashdist looks useful but it's for people who will build everything
from source (as is basically required in the HPC environments for
which it is designed). This is still problematic on Windows (which is
never used for HPC).

Conda looks interesting though, I'll give that a try soon.

The core extensions that I would want to put into each and every
virtualenv are things like numpy and matplotlib. These projects have
been reliably providing binary installers for Windows for years and
I'm sure that they will soon be distributing wheels. The current PyPI
binaries for numpy are here:
Is it not a fairly simple change to make it so that they're also
uploading wheels?

BTW is there any reason for numpy et al not to start distributing
wheels now? Is any part of the wheel
specification/tooling/infrastructure not complete yet?
