Wi-Fi Aware looks cool. Something like this has been sorely needed for things like Chromecast setup and local multiplayer games. Has anyone out there used it, or are there no supported devices yet?
Seems Google is leaving it up to the app devs to come up with services, to expect a whole lot of silos to sprout, balkanizing the system.
On that note, i seem to recall Mozilla tried to build something similar into their Firefox for Android at some point. But i can't relocate it now because i can't recall what "catchy" codename they had on the project.
