David, our group funded that effort (development by Enthought) and the code is still out there and mostly functional, but it really never got traction. The 1st phase involved major surgery on the NumPy/SciPy libraries which they needed anyway, so some good came out of it. We'd love to see some kind volunteers finish the remaining "10" percent. It would be very useful to other .Net users as well... yeah, I shed a tear :(.
