A simple .NET based server to serve a single file via HTTP, advertising it via Bonjour, written using .NET 3.5 and WPF. I basically wrote this in a day after some frustration trying to just get files over to an app I've written for iPhone.
The main (and pretty much only) purpose of this application is to provide the ability to serve single files to an iPhone from a Windows system.
Effectively what this application does is prompt for a file, advertise it via Bonjour using some fixed parameters, and serve the file itself over http on port 2595. On an iPhone (or really anything else that needs to have a file squirted to it and understands Bonjour), one simply needs to look for the service named "AuRevoir" on the local domain and extract the url and basename from the TXT records. After this, its just a matter of grabbing the file over http using the url.
