Say you have 1 Mac Book with a 256 GB SD internal drive and 1 new Airport Time Capsule. Could you really Manage 6 iOS devices with 4 different Apple IDs from that one iTunes app installation?
Also the out of the box "Convenient, Just Works" experience is that those devices are are all doing multi Gigabyte redundant downloads.
You may say that is not a problem but it simply isn't efficient for restricted Internet Access Plans. 10GB or 50 GB is often a hard limit for Rural ISP packages.
Also there are
Mobile Device Management Software suites that are solving this problem for Business.
It looks like the OS X Server Cache is the Apple solution to the problem.
That must also be why they did not put that feature into the new Airport Time Capsules. It's a reason to sell a Mac Mini with Mac OS X Server on it.
I guess that might be the only way to get the "Hands off" Bandwidth efficient experience I'm look for. After all, who wants to manage 100s of Apps for family members just to save bandwidth.
It should just be easier.

Have you tried this? How does it work? Do you have to have a dedicated machine (on all the time) for this or could it run from a Mac Book?
