Build monodevelop within monodevelop

There is a monodevelop solution in the monodevelop svn tree. It allows you to build monodevelop from within monodevelop, pretty cool. Look at the screenshot, it shows opening the replace dialog from the monodevelop GUI editor called stetic.
Monodevelop seems to be shaping up verry nicely. It will be cool to finally have an IDE that allows you to create gnome apps without having to read tons of documentation.
