Mikey Campbell, writing for Apple Insider:

Apple’s patent application for “Point-to-point ad hoc voice communication” describes a mode of communication much more intimate — and less ambitious in function — than the company’s iPhone product line.

Specifically, the invention outlines a headset capable of connecting with other devices of the same type via wireless ad hoc networks, also known as peer-to-peer or point-to-point links. Packed with a typical assortment of audio hardware including a microphone and speaker, Apple’s proposed headset also features a communications module that allows it to interface with other units in close proximity.

I think this is a pretty cool idea, partly, I’m sure, a romantic tug at memories of real walkie-talkies from when I was a kid. But there’s a practical aspect, too, when you are in a remote (or cellularly challenged) area and don’t have cell signal. Interesting.
