It appears that it is going to be a third party app and not part of ios 9 update.
Oh well, at least something that Apple approves of. We will just have to see if it will be compatible with the DJI GO app.
Crossing fingers and tapping toes.
EDIT:
Looks like I misread the way this will work. It will be imcumbent on DJI to implement this via the GO APP. It will not be a third party. DJI Dave start whispering in the ears of the people who can make this happen.
