Guy, One option that I have used in the past is to use super-sampling. You would render your scene at a higher resolution, and then perform any variation of averaging or weighting you want as you scale it down to the final size. This will help to make sure sub-pixel objects contribute to the final rendered image. One of my previous implementations just rendered a specific node geometry by itself at a high resolution and then scaled/blended it in with the rest of the scene.
