Yes, I've also noticed that once the .swf is embedded with Mochi's Live Update it becomes scalable. I don't know how it works, but I got the same result after having embedded the MMF-generated .swf into a new .swf via FlashDevelop:

I'd be glad if this could be a native feature of the MMF Flash exporter. I like old-shool games with big pixels (like many in the click community), and I'd happy to develop a 320*240 game and publish it at 640*480 for example. It's good for the filesize too.
