Man, why you always gotta steal my ideas? Oh well, I LOOOVE the idea!! I have been thinking about what type of scene format would be best lately, was was tempted to write my own. Dotscene wasn't really being actively developed, and OSM was too propritory, I thought collada would be the best approch. Then seeing Fups, and nfz new work lately has really inspired me to use it (for debugging levels, binary is still a MUST for release).
btw, I really appreciate you developing almost every idea I have ever had for ogre (using the same 3rd party deps too). At least I know someone who knows what the hell their doing is working on it. I'd still love to help though.
