I quite like the idea of dynamic shadows, it always seemed silly that my mineshaft has a beam of light reaching all the way to the bottom all day long. But considering the performance issues with that mod I don't think my PC would be able to handle it, and I doubt that it will ever be added to the vanilla game.
