My brother-in-law is a teacher and his school have just bought 30 iPads for their students. The iPads are all on the same iCloud account and they use this to share documents between the students (i.e. to make sure every device has the same/latest version of a document etc.) He's wondering if there's an easy way to 'deploy' app updates to each device, so for instance when an app is purchased/installed on one device it will sync across all devices (without him having to navigate to the app store on each device and click 'install' or what have you.) Does anybody know if any such developer software deployment tools exist??
