		<description>I agree that MA&#039;s viewpoint is exclusively cloud centric (shocking). And Michael Bernstein nails it with the P2P stack. What happens when people really do start to care about privacy in the cloud? 

Which reminds me of your discussion of &quot;lifebits.&quot; Maybe the user will eventually want to retake full control and the only way to do that is to have the application and data run from my personal &quot;datacenter&quot; and get streamed/cached throughout the cloud in a non-persistent P2P way.

Sure the application code comes from the cloud (I subscribe to an app) and maybe there is some synchronization, syndication to the cloud, but more likely through the cloud(the cloud is an essential service in connecting your personal data center with mine, and promise some degree of resilience via caching (who&#039;s TTL I control) but not all important). Unfortunately asymmetric internet connections and net neutrality issues may hold this back.

The internet is fundamentally about E2E. The cloud shouldn&#039;t be an endpoint (unless necessary for backup purposes, or caching) rather the cloud is distribution, the cloud is what allows all that level 1 connectivity to occur. In this world Facebook is runs as a local app (cross platform one would hope) so that neither the Facebook corporation ownz my stuff nor my friends who subscribe to my stream which is a non-persistent and revokeable cache on their personal computer.

But I may be clouding the issue.</description>

		<description>&quot;I think you’d have to call it ‘Level 0′.&quot;

Great point!

&quot;Instead, we will need a P2P-service equivalent to POSIX, and I would be very surprised if it didn’t turn out to be RESTful&quot;

About 10 years ago I was working on something was calling distributed HTTP: http://jonudell.net/download/dhttp.html. I still like the idea.</description>

		<description>Jon, if the lowest of the low-level APIs (storage and computation) get re-formed as a set of P2P services, &#039;Level 4&#039; is the wrong name for it, since it will (optionally) underlay the other levels. I think you&#039;d have to call it &#039;Level 0&#039;. Other strands in this thread are server virtualization and &#039;Hardware as a Service&#039; (HaaS).

But, given the premise (which I largely agree with), I think it is safe to assume that for these ideas to succeed in the current environment, the industry as a whole cannot tolerate re-proprietization of the lowest levels of the infrastructure stack (proprietary implementations of interoperable standards are still kosher, though).

Instead, we will need a P2P-service equivalent to POSIX, and I would be very surprised if it didn&#039;t turn out to be RESTful (but possibly with one or more new non-http URI schemes).</description>
