You might also examine the Reyes paper in the 86 Siggraph (I think, all
this stuff is once again, not in my office).  Reyes basically just did
a scanline Z buffer at some higher resolution, and then filtered the
results apprpriately to get an nice image.   I believe the aliasing 
artifacts will be lessened because imformation from adjacent pixels can
be used for filtering, allowing a wider filter to be used.
