I haven't done normal-map lighting yet, but that would all work in the standard way. But because this is fundamentally a raytrace through a volume, you could trace a ray back out towards the sun and get self-shadowing. Also, the surface could be fuzzy, or slightly translucent, or procedurally hairy.
