Amazing how similar this is to some ideas I've been playing with, tho
I wasn't using a coordinate system and a dynamic R*-Tree, not a grid.
I'll get back to you on this one.

If you use fixed seeds which _are_ stored in the DB, then shouldn't
the algorithm repeat when you interpolate between your fixed and known
seeds?
