asyncfileupload

I am trying to write a simple asynchronous file upload control for ASP.Net. I've tried a few implementations out there (AjaxControl Toolkit Async Upload, Telerik RadAsyncUpload, AjaxUploader, Uploadify, etc.), but they all leave me wanting something more. I'd rather not use a Flash component, a simple throbber would be OK. Some don't have client side call backs.

I figure you can make an http module that checks the request form's enctype and files collection on BeginRequest and save those files to disk. Then somehow use an httpHandler to poll the module's status but I can't quite figure out how to put it all together asynchronously. Can you help me arrange the pieces?
