I think rendering one at a time is enough (as in my first mail: one as
the default to display), with time one could include fun stuff like LOD,
subitems in the layer legend, or whatever somebody might come up with (
intersection etc).
More interesting for me is the possibility to access additional geometry
columns from a plugin, and therefore having the dataProvider ready for this.
The idea of having multiple layers, pointing to the same table sounds
interesting as well. This would probably mean separating the pretty
strong linkage between layer (as representation) <=> table (as data),
we've got now.

But how would you render that? Even if you have three geometry columns
in one table are you expecting QGIS to be able to render them all in
one QgsVectorLayer in the canvas. Or do you want a different layer in
QGIS for each column but that all point to the same database table?
