Umm, its mostly half - baked still but you can find some examples in my
twitter feed e.g.

Well even in QGIS main window you can have many canvases (but they all
share the same layers) e.g.press Ctrl-M a couple of times.  Yes I
believe in my code example it should be parallel rendering - but Nyall or
others may want to add to the story of how the internals are working
here....
