How do cross-domain restrictions work with Remote Storage? Does the server distributing the web app have to whitelist the Cozy Cloud URL?
How robust is the offline synchronization, e.g. what's the largest amount of data which has been synced over an intermittent connection? Can more than one client be offline concurrently - how are conflicts handled?
We didn't stress test it so I don't know how it would react with big files and conflicts. It's a first version to say that we are compatible with it. If people shows interest in it, we'll improve it to handle edge cases if needed.
Whatever, I imagine you could find most of the answers to your question on the Remote Storage forum and website:
