[sorry about the linewraps, broken yahoo webapp..]

see also i.vpoints for neat features like click-a-point on source and target left/right panel images, and test reverse-projection of vector layers from target location over source image. 

I would be nice to have the "auto" and "3d" i.points updated+moved from grass5 incoming / contrib code into grass6 addons, or at least well summarized for grass5 on a wiki page or so. the idea is to have a full plate of good ideas with demonstration code available while building the new wxGUI georeferencing app, thus a stronger roadmap of where we want it to go and what features to include.
