The new YUI release now includes a flash uploader that works with Flash 10. Can be used in two ways: Either you configure a sprite that the flash uses to show the button, and the user clicks on the flash button, or the flash inserts itself as a transparent overlay on top of the existing upload button. Works well, though getting express install to work with the YUI script takes a bit of hacking...
