Sandstorm is awesome, but it's nowhere near as simple as installing an app on your phone to use it. Selfhosting something like NextCloud shouldn't be more complicated than selecting it from an app store and going through a quick OAuth flow to tunnel traffic from a domain name.
The real killer for Sandstorm is that each app has to be modified to work with it, and they tend to get out of date. It just never gained critical mass as a platform.
But it had many advantages in terms of security and usability. I think if we can ever truly get selfhosting for the masses off the ground, something like Sandstorm will eventually thrive.
> What's your project btw?
It's not public yet. I'm working on the client software side and partnering with PrivateRouter.com to build out the network. We're shooting for a beta release in the next couple months.
