When this article appeared on Cult of Mac, many of my friends & colleagues forwarded it to me. http://www.cultofmac.com/271225/appreciated-ios-7-feature-will-change-world/
If this really works, why isn't the whole world raving about it? This could be a total game changer.
Now, the raving starts. A little. So maybe it really is feasible: Bringing the internet to remote areas. Or securing internet connection where many, many people want to go online through the same pipe. Maybe the world is not raving about this, because there are many huge company invested in technologies that would become obsolete? "Wired" writes about it, and to be honest, I trust the more than "Cult of Mac". And if this really works, you will see me ditching Android in a minute. http://www.wired.com/2014/03/apple-multipeer-connectivity/
