- within is available
- area is available for spherical, but not for geographic. I'm busy with that one, hope to add it soon to trunk
- centroid, and several other algorithms, are indeed not yet available for geographic.

Yes, most noticeably the intersections would be great, but that will take a little longer.

Don't know comparables w.r.t. spherical/geo. I'm a GIS person as well so GIS is getting much attention ;-)
