How should you keep stencil shadows from passing through walls, and rendering on surfaces that are behind walls? I mean, if you project a stencil shadow from a lightpost onto a building, the outside of the building will be shadowed, but the interior of the building will have the shadow inside it as well.

Otherwise (if the wall isn't casting shadows) you have to do zones or occlusion testing, and not cast shadows from the outside when viewing from the inside.
