Apple supported content caching has been around for a number of years now, I'm surprised people are just starting to hear about it. I would call content caching handy for a majority of people, and a must have for anything larger than a small business. I administer a school of 2000 students and 300 staff with a strong BYO device program. Our curriculum is almost completely online, and officially we only offer support to iPads. Our uptake has been so successful that between student-owned and school-owned class sets that 1600 iPads total have access to our network. Picture in your mind if you will, what 1600 iPads all downloading a 6 GB iOS update over a 150 Mbit (~19 MBytes/sec) link at once might do to a network. Now compare that to a gigabit (125 MByte/sec) link to our Mac Pro and 9.6 TByte saving in internet quota.
