create javascript drag and drop field; pass vars to our uploader - for mac os / 4

We need to enable drag'n'drop via javascript for the latest macs. Perhaps this can be done with javascript or jQuery. We just need a client-side prototype that works on latest macs and shows dropped files and folders. We will then need to prepare paths (as variables) to dropped files and folders for sending to the client-side java uploader. All we need from you is a working file-folder dragging prototype with documentation: - we drag a list of files and folders to a rectangle in a browser. - the dropped files and folders are displayed in an output window as a tree of files (before upload) We do not want to use java for this because this will not work on mac OS.
