AFAIK there are several scenarios under consideration.
This thread convinced me that rewarding via PUT was the most feasible. That’s not to say there aren’t other suggestions with merit though.
What’s cool about this model is if the APP gets paid with PUTs, there may be a way for that APP to give a portion of it’s profits to the content creators. That would also lead to the APP with the best average of creator rewards vs user friendliness to become most popular.
EDIT: Check out what N99 is doing and how they plan to pay content creators. It is similar to the example that I outlined.
