It's not a question of the vision, as all these features do come together nicely with a lot of benefits for producers and consumers alike.

It's a question of how you build it.

Starting as a Google Play competitor on Android, complete with Google Play Services type API for push notifications and other things, along with the subscription model and all that entails. Throw in the cloud storage for good measure, and you've got a convincing sales pitch to people.

The promise of consistent revenue gets the Developers on board; The promise of an add free, google free, try before you buy experience gets the users on board. Being a full Google Play alternative means android forks like Cyanogenmod can have a decent store with services API without being beholden to google, you can even get it on SailfishOS for all the google-phobes that we have.

Starting really small like that means you can build a service fairly organically, and then once you have a good userbase and decent revenue then it would be a lot easier to sell the idea of SoluOS to people who already have a subscription, already have the apps they love on SoluStore, and already enjoy a little taste of the social collaborative paradigm that is central to the idea.
