I could be mistaken, but I don't think the integration is through the cloud. It looks like it's built on the same tech as airdrop, using bluetooth 4.0 to exchange bonjour data then build an ad-hoc wifi network to transfer data (might skip the wifi for tiny transfers like email contents)

Otherwise, the stuff like instant tethering wouldn't work because the devices would never be able to connect - also it seemed too fast in the demo to be making the round trip to the cloud, though that is the nature of demos

Admittedly I can only make guesses as to the actual implementation. It may well be through the cloud, through some Bluetooth/Wi-Fi communication, or maybe even a mixture for all we know. Nevertheless, my point is that the concepts and the high-level integration in and of themselves are not particularly novel.

Again that's not to discount what Apple has achieved here. In typical Apple fashion, their excellent execution of existing concepts is where their value proposition lies, and this is no exception.

The cloud part is that if you handoff between a document in Pages in iOS to a document in Pages in OS X, the document itself can just be opened via iCloud rather than sending it directly. Only the user's current state (scroll and cursor position) needs to be sent directly.
