I did find this little solution: http://away3d.com/forum/viewthread/295/

I use it as a static function:

public static function getStagePosition(cam:Camera3D, obj:ObjectContainer3D, view:View3D):Vector3D 
  {
   var camT:Matrix3D = cam.viewProjection.clone();
   var planT:Matrix3D = obj.sceneTransform.clone();
   camT.prepend(planT);
   
   var pv:Vector3D = Utils3D.projectVector(camT, new Vector3D());
   pv.x = (pv.x * view.width / 2) + view.width / 2
   pv.y  = (pv.y*-1 * view.height / 2) + view.height / 2
   return pv;
  }
