I'm considering setting up Family Sharing for my family's devices once Yosemite is released but had a question I was wondering if someone here could help with. Currently everyone in my family has their own account which is used for iCloud. Then we all use my account for iTunes/App Store purchases. I'd like to switch to Family Sharing to take advantage of some of the other features it enables (shared Find My iPhone for instance) but am scared off by the fact that developers can opt out and also that things like In-App Purchases are excluded (1Password being one example concern). I've read that it is possible to have separate iCloud and iTunes accounts even in a Family Sharing environment. So my question is could I set everyone up in my family to use their own iCloud account but use my account for iTunes just like now but in the Family Sharing environment, or would the system prevent multiple family members from being logged into the same iTunes account? If I could do this, I feel like it would solve all of my concerns. Thanks in advance if anybody has an idea about this.
