RMBT, the graphical web-based program for MUD world editing that we developed for the Armageddon Reborn project, is now open source. You can download it at http://lemonlimesoftware.com/
I'm hoping to see other MUDs out there using it someday! It was a lot of fun to develop but there is still lots of improvement, so it'd be great if it became a community effort.
