Scipy has some other smoothing capabilities in interpolate (smoothing 
splines) and signal (Savitzky-Golay filter).

I'd like to see these smoothing routines collected in one place, whether 
that is inside scipy or a separate package. Perhaps a high-level 
smoothing function could be written that performs subcalls to various 
routines.
