see:
 "g.proj -p" from the command line
 "PROJ_UNITS" file in the location's PERMANENT mapset
 G_database_unit_name(), G_database_units_to_meters_factor() in libgis


In my experience reprojection on-the-fly is nice in theory, a disaster
in practice. I would suggest to help QGIS (and Arc for that matter) get
that working correctly before thinking about doing so in GRASS. 
(neither handle mixed datums well; real raster reproj is too expensive)
