Today, the potential magic of AirPlay is a little cramped in practice. Third-party video apps like Netflix don't push out video, and Macs don't push out anything, except through iTunes. A purported Jobsmail says that'll change next year.
Even if the Jobsmail isn't 100 percent authentical, if AirPlay is Apple's grand plan for your living room, it's a pretty sure bet that it'll connect more Apple products, more tightly in the future. Like multiple applications on the Mac from Safari to QuickTime X (hello Lion), and third-party video apps like Netflix on the iPad. The less safe bet is that it'll work for pushing games from your iOS device to your TV, but we'd like to see it anyway. [MacRumors]
