Check out this nice looking Flash portfolio site:
If you look at the HTML source you can see that its made up of one SWF scaled to 100% of the window size. Yet there is no messy / blurry anti-aliasing on any of the screen elements. Further more, when you re-size the window the various elements of the Flash movie seem to move as if they were absolutely positioned CSS elements rather than things inside a Flash movie … how on earth is this done? Does anyone know??
