I'd be happy with an algorithm that's specific to ranges, too, but my 
gut geeling is that there has to be a lot of research on spatial join 
algorithms out there. Implementing one of them would be more widely 
applicable, so I think we should look into spatial join algorithms first 
and see how far that gets us, before we write something specific to ranges.
