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.
