  It would be great to see a simple example script of how to find all the vertices that would be affected by the movement of a bone.

  Well, I found the selection map, but I think somehow doing this with the weightmaps would be awesome.  I think the selectionmap is just used to get the bone to select based on the face clicked or something?

  Also, I don't see it clearly documented anywhere what the indices of dzFaceGroup are.  I assume they are indices of the vertices in the geometry?

  This was the little script I ended up with:

  var selmap = female.getSelectionMap();
  var dobj = female.getObject();
  if (dobj != null) {
    print("shapes ----------------------");
    for (var j = 0; j < dobj.getNumShapes(); j++) {
      print(String("---- Shape %1").arg(j));
      var dshp = dobj.getShape(j);
      var geo = dshp.getGeometry();
      for (var k = 0; k < selmap.getNumPairs(); k ++) {
        var fg = geo.findFaceGroup(selmap.getPairGroup(k));
        for (var l = 0; l < fg.count(); l++) {
          var v = geo.getVertex(fg.getIndex(l));
          print (String(" vert:%4 X:%1 Y:%2 Z:%3").arg(v.x).arg(v.y).arg(v.z).arg(k));
        }
      }
    }
  }

  Unfortunately DzShape is not currently documented, my recollection is that you could get a list of weight-maps affecting a given vertex but it's not a feature I've used so my recollection is hazy.
