As Bill mentioned, we use a Display side CS in MetApps.
See ucar.unidata.view.geoloc.MapProjectionDisplay.  This
will take either a visad.georef.MapProjection or a 
ucar.unidata.geoloc.Projection as input to set the background
projection.  For a version of MapProjectionDisplay that
uses vanilla VisAD (i.e. no Unidata classes), see:

ftp://ftp.unidata.ucar.edu/pub/dmurray/MapProjectionDisplay.java

This does not allow you to change projections, though whereas
ucar.unidata.view.geoloc.MapProjectionDisplay does allow changes
by creating a new DisplayRealTupleType with each change.
