this is very close to an inventory control app I built at work (with the exception that eventually when the client is online it will sync data to the server). I've often thought, if I had the time and capability ... take it a step further. No server sync at all. Clients form a peer-to-peer network and sync data between themselves. (perhaps bluetooth or something like Apple's Bonjour etc) Actually something like that, plus an optional server sync when server is available is really even better. I'm thinking specifically of a use case in large warehouses that often have no internet connectivity but in which there are multiple users performing inventory who are duplicating work because they don't know a peer already inventoried a specific area and neither of them can sync to server because no wi-fi. dang even better. something like a bit-torrent swarm with something like an admin certificate for releasing code patches, and user-level certs for syncing app data.
