Apple AirPlay like fuctionality with Xbox One and Windows 8?

So now Microsoft has announced the Xbox One and revealing Windows 8.1 will Microsoft be bringing AirPlay like functionality to the Xbox One for Windows devices? Apple have had this feature with their entry to the living room with Apple TV. I think this is a really nice feature and something which I'm quite interested in, has anything been said about this at a conference like Microsoft's build? Or if Microsoft aren't bringing this feature do you think it will be possible for someone to make an "app" for the Xbox One?
