When Chris Brunsdon and I were in Lucca last September, some coding was
done, although it isn't yet ready for release. Some more work needs to
be done, also to introduce geographically weighted statistical summary
measures. The code does include the k-nearest neighbours adaptive kernel
used in GWR in some cases. If others would like to join in, I could
start a sourceforge project if you like.
