Interesting...I did not realize they allowed non-raytracers.

Examples of the current rules, the ones which we are discussing changes 
to. I would find tinting the sky acceptable. Lens flare...perhaps. It 
obviously can't be prevented if it is done within the scene as textured 
discs or actual camera optics. I'd say 2D lens flares are OK as long as 
it's not hand-positioned. 

Motion blur (and other types of blur): this really can be used to 
simulate real blur effects caused by scattering in the retina or sensor. 
I'd consider it borderline. If any effect is allowed with one package, 
it should be allowed with all others.

A competition between artists with tight constraints on how the images 
are to be produced. It wouldn't matter one bit to the competition if 
everyone used the same package, because the entries are images, not 
packages. Packages aren't scored, the actual works are. You win by 
having a superior image, not by using superior software.

No it wouldn't. Such an image would be a source file, not a modification 
to the generated image. Of course, someone could put an image_map on a 
plane and point the camera at it...I'd rely on human judgment to have 
such entries thrown out.

No, that's not what I'm saying. I'm saying that it is the algorithms 
used to generate the image that matter, not the software packages. The 
final image should be renderable from all source files without human 
editing. (Again, with the exception of signatures/watermarks. Anything 
goes for those, as long as they're unobtrusive.)
