I created a very simple module to gracefully handle uploads inside of DotNetNuke (DNN). It uses the SwfUpload control which is a flash based solution for uploading extremly large files through ASP.net. Currently it's built for DNN 5.1.x or greater. Below you will find a few pictures of the module in action, sorry I can't provide a live demo at the moment. You can download the SwfUpload module for FREE in my Downloads section.
