Sorry for sending this twice, the first time my Outlook flaked out and I thought it hadn't send it.

Depends on what you mean by "falls down". I have an experimental map which does even rollover highlighting using all client side javascript hit testing. Point your Chrome (or Safari, Firefox is just ok) to:

http://13-9.com/c2

Performance is not *that* bad given that it does a hit test on every mouse move, not click. (Use left click to select, mouse wheel zooms, middle button drag pans the map)

Yep, even Facebook and Google are dropping IE6 support, actually
I believe Facebook announced they would drop IE6 support the moment
that Microsoft released the first beta for IE9.

If we are going to do more vector based rendering in the browser, we
really should look at server generalisation support within MapGuide.

on the fly generalisation (excuse my aussie spelling) but also
perhaps caching those results to an intermediate sqllite cache
similiar to the tile cache.

also gzip/deflate encodings + cache headers come to mind

and of course this would also benefit our existing rendering technologies

Canvas in OL is great for dumb layers, but doing stuff like clustering
falls down because each click involves an R-Tree search.
