The easiest to get started is to copy the setup structure from another scikit.
I think the template scikit in scikits svn is a bit out of date, the
last time I looked.

If you think your model could form the basis for enhancing the
smoother or noisy interpolation category in scipy, then a scikits
would be the best way, as we discussed.

If you want to add it to an existing scikits, then statsmodels would
be a possibility.
Although statsmodels is more oriented towards multivariate approaches,
I think a smoother category, together with some non-parametric
methods, e.g. the existing kernel regression, would be an appropriate
fit. There is a need for smoothers in gam, Generalized Additive
Models, but that one is not cleaned up yet.

And I think there will be more applications where it would be useful
to share the cross-validation code as far as possible.
