I don't think we'll be able to avoid that hurdle; we'll need to make sure that the protocol is really simple.

But having to know the data format of the app itself is to be expected. If an app "instagram-on-solid" stores data in a certain way, the alternate app will need to understand those schemas as well to be compatible. That's how interop has always worked, even in the pre-internet age when we were exchanging files on disk.

I haven't looked at apps in a while - but that was indeed moving very slowly.
