Open Source Network Servers in C#

NeatUpload allows ASP.NET developers to stream uploaded files to disk and allows users to monitor upload progress. It is open source and works under Mono's XSP/mod_mono as well as Microsoft's ASP.NET implementation. It features 2 custom controls: InputFile allows the user to select a file to upload, and ProgressBar displays the upload progress either inline or in a popup. ProgressBar even allows users without JavaScript to see upload progress.
