A: Very simple, just a couple of clicks, first create a collection in this source LightCuts camera collection, place the objects you want to share with other cameras, and right click the collection → Instance to scene (you can add this to your quick favorites (Q), it's one of the most practcical ever in computer graphics, and blender.) Then just place this Collection Instance in the LightCuts camera collections you need, you can edit those objects in the source collection, and they will exist / be seen in the other cameras you chose:
