For N-d smoothing, there's this:

which seems a bit similar to regularization smoothing.

That might be a good idea. If smoothing is well-defined enough, it could 
be separated from interpolation. For instance, much of the spline stuff 
could be copied there, and the corresponding routines in 
scipy.interpolate be deprecated. Parts of the FITPACK stuff seem more 
smoothing than interpolation-oriented...

But really, there would be room for an expert to suggest which smoothing 
algorithms would be those most needed.
