This is the main area where I suspect Google's greater reliance on clouds leads them to castrate their operating systems. Last time I checked Chrome OS still didn't even support Bonjour mDNS. (Still the case, and it's related to this first mentioned in 2009: <a href="https://code.google.com/p/chromium/issues/detail?id=13573" rel="nofollow">https://code.google.com/p/chromium/issues/detail?id=13573</a> )<p>The Android stuff alone is an inconsistent trainwreck (because not all hardware supports all options on a given version of the OS either) and it took them a long time to get there.<p>Apple really have been leading the sane local peer-to-peer world ever since Bonjour first appeared, and the new developments have just extended their lead.<p>It will be interesting to see just how this difference affects the nature of their respective wearables.
