Are there any special considerations that need to be made with regards to synchronization? I'd expect the DBs to be mostly read-only, so maybe it won't matter much. But I'd hate for a write conflict to leave things in an inconsistent state.
Edit - Thinking about it more, I suppose it really depends on what each cloud provider does.
Yeah you gotta make sure you're syncing the db properly when you write to it. It works ok with two people, but it doesn't scale much further than that.
