Drag and Drop File Upload

I'm looking in to a solution that ties in with PHP that allows uploading files via drag and drop. So far, I've only located a Java applet (Thin File) as a possible solution.

I'm wondering if anyone knows of an uploader that uses AJAX or Flash.

Thanks

jQuery has drag-n-drop capabilities; that's where I'd look.

Flash might be able to. Ajax/Javascript cannot because the type="file" form field is read only and javascript cannot set it, nor can ajax/javascript upload a file by it self.
