Drag and Drop File Uploader PoC

I went nuts trying to understand this and get a working example. I'm not a JavaScript guy, but I wanted to do this without fat libraries and plugins so that I could integrate this with existing systems. 
It uploads exactly the same basic way as existing code in a system. Just the UI is very different. 

Credit goes to Mozilla for good documentation like: HTML Drag and Drop API

 Drag and Drop Javascript PoC / draganddroppoc.html is the working HTML page, except that files don't actually upload (no target in.php on the server). On purpose. I don't want your files. 


The raw code:
My Drag And Drop File Uploader in Minimal JavaScript - This is a starting point. It needs sanity checks, authentication and input detainting.
 As I turn this into what will be a small part of ring-u.com upgraded fax services, all of that will get added.
