I usually try to do a Box per person in the house, with an extra for a guest. Then I give them the choices on one of the main screens, I just label the boxes as Mom, Dad, Johnny, Sue, Guest, etc. That way whoever picks up the remote in that room can watch whatever they want from their own box without having to dig through too many menus.
If you try to give every one their own page with their box plus the other equipment, you are going to end up with alot of extra pages.
If you have more than that, I have made a single Cable/DTV button that takes you to another page with the different boxes to choose from.
