For your intertest...
To see the bare bones of it though, there is a new web project in the source code for prototype work and I first implemented the control there, there is this example page that hosts the control as well as an example service url to handle the file upload with no security since it is only meant for proof of concept on a dev machine. This prototype web project is much more light weight than running the large mojoportal solution. There are still a few things I need to finish on the upload control before the next release though, even though I've gone ahead and replaced NeatUplaod with it.
The css for this was added to the /Data/style/common/style.css
