Super cool doom engine - plus, has anybody written a wad file exporter for blender?

Hey guys, I just wondered about your opinion on this project:
(it’s a cross platform, open source, doom game engine port with 3D model support and OpenGL rendering etc…) - I just found it and thought it looked cool :D. But also, more blender related… has anybody actually written a wad file exporter for blender yet or is that just one of the long list of “might be useful” features? :confused: 'Cause I’m thinking I might like to write a game using the engine above (actually, I’d like to port an existing game that uses the legacy doom engine because the legacy one’s so rubbish :D) - just I’d like to be able to do all the levels and stuff in blender… :cool:
