Dunno if anyone cares.. this
took about 10-15 minutes to get building.
It works, mostly... the one issue is with Trebuchet on the left-hand "pane". Sweeping across Trebuchet leaves "tracers" of icons behind... and the background disappeared too. I'm guessing it's not enough video memory.
But it does work amazingly well as you can see below. the first image is angrybirds/market/and twitter running simultaneously.
and here we have the settings/application selection in Trebuchet/browser all at once.
