Could Apple be gearing up to improve on the video chat capabilities of FaceTime? Folks have discovered the “AllowsMultipleConnections” key in the Service Properties, implying that Apple might be looking to enable multi-user FaceTime calls. The setting is currently set to false, though attempts by hackers to enable it haven’t revealed any new features yet. Perhaps it might be related to video chat on the iPad, since the larger display would make multi-user FaceTime calls more practical, though we’ll still have to wait for the mythical camera-equipped iPad to surface before it becomes possible. Will Apple be revealing such a feature in the upcoming Mac OS X Lion preview event, or will this be something that will only arrive further down the road?
