With the web browser, we have really figured out a good flow for how one device (the “server”) can provide an experience on another device (the “client”). This raises a fun idea: imagine if servers and edge devices could serve up a browser-based graphical “shell” so they can be used from other devices. The shell would provide a home screen of apps. In this shell, every app is a small HTTP server, serving up a web user interface. The shell would provide an API so that apps can look up each other’s URLs. For example, apps could register themselves as a text editor, so you can double-click text files in one app to open them in the editor app. These graphical apps would be an alternative to terminal-based apps. These HTTP servers will typically be private, inaccessible to other devices on the network. Instead, you’ll use them over SSH, or locally.…
