For example in the demos/breakout there are simple "spot lights" that are for visual appearance only. It'd be nice if this type of thing could really be used to compute light effects. For example in the same demo the individual tiles could simulate being lit or being in the shadow by seeing how much light falls upon them. This would mean having to rasterize the "spot lights" into some buffer that can be used to rasterize the game tiles.
