With the advent of real-time lights and shadow mapping, I can see how this could really be beneficial to workflow. I don't think your going to want to make multiple light sources for nicely lit outdoor scenes when a SSAO shader can cheaply produce the same or better results automatically with one source.
I really like the effect and simplicity.
Create the your "sun" light source and move it depending on the time of day. All your shadows are updated and fake ambient occlusion happens also, no going through gile[s] again for the night scene.
