As someone working on something that i think is somehow related to both Sandstorm and Solid(at least in some of the key goals), i've turned into a distinct path.
The most reasonable thing to do, of course is something like Sandstorm did. You get the technological 'status quo' of the web and mix it into a self-sustained, autonomical node.
I think that when you need to have this level of autonomy, the design meant for the web doesnt solve this very well.
This is the reason why i think both Sandstorm and Solid didnt 'hit the nail' yet, because we need a couple more "iterations" to solve this in a more satisfying way, and it goes deep down into the architectural choices.
Having said that i think Sandstorm, Solid, DAT and IPFS have the right mindset, and the sort of meditation that are pointing us to a future.
The real danger here, is that the web on its own will get trapped by the mobile walled gardens of both Apple and Android were you dont have any choice of distribution or reach without saying yes to a digital overlord that can terminate your channel within the digital realm over any bogus reason presented.
And unfortunatelly our legislators are still not prepared to deal with our current digital citizenship and to make the proper stand on our civil rights.
Without a proper solution, we are heading to a dystopic digital feudalism, and this is one of the reasons why im also working hard to launch something that will at least try to make this dark looking future not so unavoidable.
(And thats why i have a utter respect for projects like Sandstorm and Solid)
I repeat; The web stands no change and will become a "channel" within a bigger internet ecosystem, and a symptom of this is the web being embedded as a app platform for mobile and in the near future desktop apps.
The web has a great future as a application platform, but this free, utopian world where we have a more free and descentralized way to share information is losing a lot of ground, and if we dont keep some great values the web stand for in new tech incarnations, we stand no chance to keep all this.
