"Please Google, destroy Zigbee. Zigbee 1.0 was patented and not GPL compatible. Zigbee 2.0 picks up open 6lowpan and then patents the application layer again closing it.
Please give us an equivalent to the Smart Energy application layer free of patents."
excellent comment and great article from here:
But I still didn't see anything from Google but their marketing stunt at Google IO. AFAIK there is no spec released, no licence under which it will be under... if anybody has more info please point me in the right direction.
