Here's my little addition to the Reality thread.  Not a full Lux render but a SLG render that I let run overnight.  Can't seem to commit to a full 20+ hours for a minimum of 500 passes on a decent sized Lux render.  It's a pretty simple setup.  Model, clothes, scenery, 2 lights(sun and single spot) and render.  This ran like 1930 passes.
