Don, it works pretty well if you already have your management zone maps in JDO.   The thing that people using other software expect is to be able to easily import actual Rx shapefiles created in other packages, without needing to go back in and recreate the rate classification tables.   In other packages, if you have a shapefile with polygons labelled as 30,000 then when you import them, you are done.   No need to reassign the 30,000.

But, as Noble1 is already setup to go with another program, he can easily use his GS1 for vra, w/o doing any kind of import/export into another package.
