Well, it seems to me that Mr. McFadden is far more knowledgeable and skilled in game engine development/porting (at least with the Quake 3 engine). There is no doubt that he is already an incredible asset to the Maemo community and what I personally wish to see is more playable games on the N900 using ioquake3 (or a modified version). I believe he could do that rather simply (keyword: believe), he is the expert not I. As far as lighting goes on his previous work, there will always be men to stand on the shoulders of giants to fix the little things.
