I think this is a good idea. My only concern might be how to determine the threshold for 'massive'? It can't be just number of features ... a single feature can also be too massive for IE. It might get quite expensive trying to determine that threshold by counting nodes in each feature though.

in terms of the selection handling in Mapguide, it's pretty klunky at the moment and involves multiple round trips and re-rendering the entire map.
what do people think of switching to return geojson or kml and rendering the selection as a OL vector layer? Including a fall back to the existing process for massive selections which IE can't handle?
