I thought iCache was going to be a horizontally scaled database service that all game servers would be able to access. From the recent Calling All Devs episode it sounds more like each game servers will have its own iCache instance on its drive for quick read/write speeds to the database. Each iCache instance would replicate relevant data from the main global database based on which sections of the game world are loaded on that server. Will meshed servers access each others database to access data or will they constantly exchange relevant data directly between each other?
