Oh yeah, that's the best part I forgot to mention, the sharing function is awesome!
Me and my sis got an XBOX One each, we bought CoD Ghosts digitally and are both sharing it along with the season pass. We are also sharing Killer Instinct and Forza 5.
How it works in a nutshell.
My "HOME" console is at my sisters, and my sisters "HOME" console is the one I play on. Whenever I buy or download DLC I need to do it at my "HOME" console, and whenever she buys she needs to do it at hers. This way we're both sharing items together.
Works perfectly so far. Love splitting games with her...much much cheaper than having to be one each.
