I'm currently using a variation on an R*-Tree.

Why, yes!

If you look back in the archives there has bee some discussion of
R*-Trees and various other structural forms.  You may also like to
look for the neighborhood thread which proposed a significantly

Yup, except that I'm going 3D all the way.
