This is very interesting, and relevant to my current work. I would love to
see a nice generic clustering library in Boost. I can't promise much help at
this point (I also have a project I've been meaning to pick up again Real
Soon Now :-) but let me know when you start working on it again.

Clustering and spatial indexes have some close connections - as you say,
spatial indexes can be used to improve the performance of some clustering
algorithms. Likewise, clustering is sometimes used to construct spatial
indexes (agglomerative clustering, hierarchical k-means). So, it would be
nice for the libraries to play nicely with each other... but more important
to get the core functionality in place first, of course.
