I am confused by why using OpenLayers is okay, but using MapServer is
not. In both cases you are adding your own content to Google Maps
content. With OL it is being done on the client in the browser, with
MapServer it is being done on the server and passed t the browser. But
the net effect seems similar. So why does Google care how you do it?
