One of iPhoto for iOS’s most useful new sharing features is called Beaming. It lets you send your photos quickly and directly to anyone sharing your Wi-Fi network and also running iPhoto.
As good, long-time Mac users we remember the bad old days of networking, where getting two Macs to talk to each other was all but impossible, and hear-tearingly frustrating at best (even when they were joined to opposite ends of the same Ethernet cable). Clearly, something has changed. So just how does iPhoto Beaming work?
