This seems like serious rumor material to me! I think the "shared memory extensions" he's referring to allow the mmap'ing of a window region into an app; if so, he can do anything you can do with a flat frame-buffer interface, and just as fast as if it were running under DOS (well, that is until it gets preempted to run the other 50 processes on your machine -- then again DOS is "safe" from that.... 8-)).
