Haha, fair enough. If you do need to write your own interpolator, note that you can still use scipy.ndimage.spline_filter() to generate the coefficients.

You could then, as I mentioned, write a Cython module to erect all the "infrastructure" in parallel to do the interpolation, or perhaps you could even figure out how to vectorize it in pure numpy. (Perhaps that's not hard to do...) If you do either, definitely drop a line to the list because I'm sure folks might be interested in the code.
