file upload with scriptaculous and code igniter?

[eluser]thurting[/eluser]
In the past I have used an iframe to upload a files while retaining state on the current page. When the frame reloads I combine it with a bit of ajax to dynamically display/delete the uploaded file on the page. I haven't done this in a while, but I am pretty sure I did it with Prototype and Scriptaculous. I could dig it out for you if you want.

edit: i found the files... PM me if you want them
