Controlling Cubasis on separate iOS device

I realize Apple has so far been blocking the option to control one iOS device with another.

I was just wondering if anything has recently changed concerning this issue with the launch of iPad Pro and the new IOS9. It would be a treat to have Cubasis running on large iPad Pro and to be able to control what’s happening on the screen with either older iPad or even iPhone. This would basically enable also the kind of remote mixing setting Cubase now offers with iPad remotely controlling the workstation DAW.
