Rumor has it that Microsoft's Xbox One console will feature remote play through Skype, allowing someone to remotely take over gameplay on the local console directly from a Skype call. Either player may break the remote play session at any time.
Supposedly the feature is in testing phase right now, though Polygon's source notes that certain details are still up in the air – like how long that individual can remotely play or whether they need to own the same game or not. During the Xbox reveal event, Microsoft unveiled group Skype calls using the Xbox One's improved Kinect sensor.
