I'd also be very excited about this project. Especially if some GIST or similar index could efficiently search for vectors "close" to other vectors. I assume something like "within a n-dimensional bounding box" would be possible with GIST.... I'd be eager to help, test, debug, etc; but probably aren't qualified to take the lead on such a project. ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
