I have in my Rembrandt TODO list to restore the use of a near and a far camera to reduce z-fighting. But Rembrandt needs a monotonic depth buffer, and erasing it in the middle of a frame is not an option. So I think we can render the near camera using a depth range (see glDepthRange) of (say) 0.0 - 0.1 and the far camera with a range of 0.1 - 1.0. This will have the advantage to allow the near camera to be rendered first. Mathias or Tim also suggested to look to logarithmic depth buffer but that is more demanding and needs a shader for all geometry (already true for Rembrandt, but not for the classical renderer).
