A while ago I made a demo of a P2P chat application that runs on the beaker browser and uses the experimental P2P APIs. It's running at dat://feathers-chat.hashbase.io (slides from the talk at https://vanjs-decentralized.hashbase.io). If the peers can see each other you should be able to register with any email address and send chat messages between browser instances.

What I realized is that this technology ticks a lot of the boxes of what we right now think only the big cloud providers can do. By using a more decentralized protocol it is by design

- Actually Serverless

- Offline-first

- Real-time

- Auto-deploying

- Live-updating

- 100% uptime

I really think there is something there from both, a developer and user experience perspective. The problem is that a lot of it is still very experimental and far from the usability and maturity of e.g. a Firebase or Heroku.
