  Progress on this has been minimal: I managed to create an ogr driver 
with a new name! There's a few places that you need to edit to link in 
the new driver in the ogr build system. Then I started to worry about 
how to link in to libR.so and stopped there. I need to find out how the 
OGR build system works with other library dependencies, and that 
probably means understanding autoconf... Beyond me at the moment...

  Isn't the ultimate in linking and brushing GGobi? There's a link from 
R to GGobi for displaying R data in GGobi. What might be nice would be a 
GGobi plugin for Qgis - set up so that brushed items in the GGobi view 
are highlighted in the Qgis map.

  I've looked at the C code in the R-GGobi interface and it looks very 
difficult....
