I guess this is count as a finished project.
I recently made a tool which you can load your world blend file and view it as a person walking in your world mesh. If you have played World of Warcraft or Second life, i basically made a tool which you can load your mesh as the world and you can pick characters to walk inside it.
I am currently programming a game using mostly blender, and i thought i can release this part of the program since it might be useful for people. Especially for people using blender . You can download the tool here http://iamar.chieh.googlepages.com/downloads
Screenshots and example videos are here http://iamar.chieh.googlepages.com/blenderworldviewer the documentation on how to use it is here
The game i am currently programming is the main website , and it is at iamar3d.com . The screen shots for my game is here http://iamar.chieh.googlepages.com/foto
The programs are completely free for you to use, I also provide the blend files so you can play with it. If you also want the blend file for the characters, (fully animated and rigged) you can download it here
that's about it, i hope people can find some use for it...
