It looks like the RNode firmware does exactly what you're looking for with its "RNode Bootstrap Console": https://unsigned.io/rnode_bootstrap_console/ https://unsigned.io/rnode_bootstrap_console/ Documentation is surprisingly hard to find, but from blog posts on the site it looks like if you press the reset button twice within one second, an RNode will turn into a WiFi access point and host this website. From there, you can download everything you need to create and use another RNode (including Reticulum, Nomad Network, and Sideband). I find this notion of RNodes being self-propagating really compelling!
