Every user in bittorrent network is self-hosting. All it takes is to launch an app.

Evidently, if you combine content access platform with a hosting platform and make running the latter a requirement for the former, it works out.

Self-hosting for mobiles doesn't even reliably work for torrents. I frequently can't seed torrents from my phone.

If, theoretically, there would be a way to resolve domain name to a specific phone, I can see self-hosting site apps getting popular.

Nowdays there are a few solutions (phone hosts a site, shows QR-code with its current IP and a port, and you can actually open the site in browser), but it is mostly for "right there right now" solutions. Site will go down the moment this phone changes the tower.

The best example of mobile hosting I have found, comes from AmnesiaVPN team. You have to rent a server, but then you just feed server IP and password to an app, and from there the app controls the server.

I imagine a future where big VPS companies started to make apps that made buying domain name, renting a servere, hosting and backuping a basic website/forum easy. It's an unlikely future, but a fun one
