SQLite has an optional R-Tree engine. The R-Tree is a new addition and has not appeared in any release of SQLite, but it is available via CVS. There is little documentation other than a README file in the source directory. Nevertheless, an R-Tree is specifically designed to solve the kind of query you describe above. If you are willing to work on the bleeding edge, you might want to investigate SQLite's R- Tree capabilities. D.
