Is the upload function opensource?

Is the rtMedia upload experience (drag into box, with % complete bars) written special for rtMedia, or is that code open source and available somewhere else?

I'm working on a different project and love the way that works. Curious if it's available to be used in a different plugin.

@kennypetrowski - We are using plupload for that part. The following link may help -> http://www.plupload.com/example_queuewidget.php
