Snapping in Blender like Silo

I heard that Blender is getting some upgraded snapping functionality. Would it be possible for the coders to make features similar to Silo? (See videos at http://www.nevercenter.com/videos/index.php?vidclip=snapping_manipulator.mov and http://www.nevercenter.com/videos/index.php?vidclip=topology_and_snapping.mov&artist=Walter%20Behrnes)

The snapping along a surface’s normals is really awesome!
