/>Not trying to be snotty, but perhaps using postGIS <<a
href="http://postgis.refractions.net/">http://postgis.refractions.net/</a>>would be a suitable alternate ? It does
requireadmin rights to install but the point does have an equality op, GIST indexing and is reasonably light-weight in
diskspace.<br /><br /> Ok, you probably already rejected this for good reason ... back to the real thread.<br /><br />
