Improving selection handling using OL vectors

zspitzer
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?

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.
