Any way to use object to occlude geometry in render??

Does anyone know if there is a way to use an object (poly cube for example) to occlude sections of a render? I'd like it to effect per pixel, not per object.

2 different method/results I'm thinking of where it occludes:

a) anything behind it (saving render time instead of rendering the whole thing and doing it in composite with a matte layer) I know there's the 'make a surface shader object in foreground' option, but am hoping there is something better...

and

b) anything inside the occluding object (for example a giant cube to make a cross section of rendered geometry) Key point being you can animate it. I think you can do that with booleans keeping the history? (correct me if I'm wrong) but that isn't appropriate for animating a cross-section of multiple objects in a scene.

Thanks
