Rhino plugin?

This Development really doesn't make the slightest sense to me.
Rhino-Users were better served by many orders of magnitude with direct Links to Programs such as 3DCoat and Zbrush
(as they are possible through both programs SDK's). Rhino lacks absolutely everything required for Sculpting. All this has
to get provided by the Plugin.

OK, there actually seem to be a conceptual difference when compared to classic Sculpting programs.
Although looking like Voxels this is actually another Geometry-Type which (as they say) has infinite resolution.
Also they follow a parametric approach, Geometry is editable from a Construction-Tree.
