Just a side comment: ActiveState is distributing (since June)

"New packages for data centric financial modeling and scientific
computing applications (available in ActivePython Business,
Enterprise, and OEM Editions):
    * NumPy: The fundamental library needed for financial and
scientific computing with Python
    * SciPy: A suite of scientific tools for Python, depends on the
NumPy library
    * matplotlib: A Python numerical plotting library
"

because of changes in US financial regulation. So maybe we get some
additional testing out of it.
