Hi,
I've searched the mailinglist briefly, but couldn't find news about geodetic 
implementation.

Are there some news about this item, unreported or reported?

One more question (from a rookie of this subject).
Are we talking about implementing ECEF support, or something else, to get full 
geodetic support in PostGIS?
