I am interested in the olite code. I hope to have more time in the future to experiment with it better.

I added the -nodust command line option earlier today. This does the same thing as the equivalent debug flag, but it does it in a much easier and more accessible way and can be used in any flavor of the game, be it deployment or test release.
