But you still can't do what he wants to do, which is pretty straightforward:

1. Photos he takes are added to a library automatically (for internet connected devices).

2. That library exists in the cloud.

3. He can access that library from all of his devices.

I also have this problem, and I'd add a 4th point: Please let me back up the cloud based library.

You can't do this with lightroom, either.
