Mark Twain wasn't quite right here, but close. When I worked at Apple, I learned that retail spaces were measured by revenue/square footage--mostly since they liked to crow about how they were number one. The store I worked at was usually number two or three in the country in revenue, but never number one. Number one was always the 24 hour store in New York. Being closed eleven hours a day made it unfair.
I have been working on a specific kind of networking of computers for a while (click the purple square above to head back to the top of the wiki and read more about it), with the thought of being able to use extra compute in people's homes to help make people money. When my wife and I bought a space, and she wanted to establish a coop there, it seemed like a great opportunity to give the idea a thought.
The service the space provides is only really relevant 4-6 hours out of the day, so having it be profitable at all is a challenge, and there's a real desire to keep costs down so that the service provided is accessible. But if we can stick a computer on a shelf somewhere that makes money 24/7 just by being on, then we're on to something.
Now imagine that all the cooperative organizations with spaces have a network of these machines, all paying money back to the cooperative. Since cooperatives pay their profits to the members of the coop, aka labor, this is the technical way of distributing surplus value to _labor_ instead of capital. All it takes is a group to provide the software capable of running this network as a sort of worldwide cooperative for people to organize with. And that is what Planet Nine is.
Where surplus value is distributed is the underpinning of different economic systems, but those have incredibly loaded names and preconceptions, so I'll leave it to you to assess what's really going on here when I say we're "socializing" the cloud.
