Drag and Drop interface

[helloworld]

I would like to create a drag and drop interface for a textarea without any server side programming. In other words, I want to do this with only javascript, html, and css. How can I do this? I do not have a host yet, so I couldn't give a url. My code right now is just an html form with a textarea. I also want the drag and drop interface to work as a form and post to an XSLT stylesheet.

maybe something like this?
http://demos.mootools.net/DragDrop

alternatively there are other js libraries that do similar drag/drop effects
JQuery (http://interface.eyecon.ro/demos)
YUI (yahoo's user interface)
script.aculo.us

let me know if those help, i would love to see a demo and how you use it :D
i plan on incoporating it on my site for user downloads like this:
