A friend of mine, Scott Swisher, passed along this information.  I thought others might find it interesting.  SharpDevelop is an Open Source IDE for .NET development.  While not complete, especially for ASP.NET, it is interesting to see where they are going with it.  I haven't played with it yet, but I plan to.  Has anyone else used this?  Any interest in such a thing?
