Yeah it is pretty cool.  That is where I first got the idea from.

My main idea was to have a QGIS implementation of that that can sit on top
of any QGIS layer not just OGR ones.  So instead of having a backend of
OGRFeature and OGRDatasource it would use QgsDataProvider and QgsFeature.

It's pretty cool that there is a Python way to do this, will be good to
prototype something quick then port to C++ for speed.  I might have some
time tomorrow to try my hand at something basic and if it works we can
explore it further.
