That's not visionary only because that's what Facebook should have been from the beginning. All early internet protocols where distributed before the web became companies playground and Conway law followed. I think a visionary replacement will happen when something will just replace the cloud (which is too often a data ghetto) by giving users a way to easily and completely control their data and services, local as well as remote, in a homogeneous and synchronized way. A merge between the two approaches: "everything on the web" and "everything on your computer". Data (and metadata) and services being identities, media, documents, events, tags, access rights, version history, and links between all those things... So all this without giving all your data to google :)
