> #3 I'd like contributors to always retain access control of their photos and videos - they can revoke subsets of their files from the dataset at any point.

I don't understand. If the dataset can be used by other people (you, the owner, and other people) then you can't force everyone to delete the photos. They can pretend that they deleted the photos and avoid using them publicly from this time. This is similar to the API in Tweeter that make you pinky promise to delete the deleted tweets. But there is no delete button in the Internet, only a hide button.

The access control is non-negotiable. Compute solutions will have to be distributed in a way that they can work with it. For example, first few layers of a neural network can be computed locally on contributor machines and transfer only the results of the calculations.
