I could be wrong but I think he wanted mostly feedback and feature requests rather than C++/Ogre gurus, although I'm sure he'd be glad of any help in that area too.
You could be right, although I don't see how making it a closed source project, is going to improve the ammount and/or quality of feedback and/or feature requests.Anyway, since he AFAIR started working on it as a direct competitor to Aurorororora, copying that feature set would probably be a good place to start. Personally I have no use for a 3D module at this time, and have far too little time to commit to BlitzMAX programming in general to be of much use - although I'm sure it's an interesting project.
