@polymerwitch@toot.cat Thats a good question. I've been keeping an eye on that space but haven't seen much.I hadn't heard of 'nearby' before, but it looks like opengarden's meshkit (they built firechat's p2p app commonly used during disasters/protests) https://www.opengarden.com/meshkit.html But its not open source.I'd been tracking openpeer but they stopped their product development & pivoted to an app.A search of competitors for that meshkit suggest that https://github.com/servalproject might be worth looking at?

@polymerwitch@toot.cat I can't find much on the 'ultrasonic modem' aspect of nearby, but there is a BLE beacon system sdk online here: https://altbeacon.github.io/android-beacon-library/index.html which is compatible with that "eddystone" protocol that google's becon system uses: https://developers.google.com/beacons/ (they have it on github too: https://github.com/google/eddystone )Might take some elbow grease to get it going in an app, but seems like its more than possible to recreate.

@polymerwitch@toot.cat Took a while to find a sound based modem, but turns out I have some friends on facebook who are really nerdy about software defined radio modems and ham radios to point me in the right directionhttps://github.com/quiet/quiet looks like its open source and the .js bindings have an 'ultrasonic' mode, and there are android/ios compatible versions as well. I was also suggested that I take a look at http://www.whence.com/minimodem/ but couldn't confirm if it can support ultra sonic or phone apps.

@polymerwitch@toot.cat Looks like you could use the two systems together (BLE modem + SDR audio modem) to set up the initial peering and then use that to exchange keys, then swap over to wifi+serval to save battery. Still a bit of work, but you'd get a good "local" experience via temporary location based mesh nets that would rival what 'nearby' can do (and all open source afaict).bonus: have fun making your cellphone make funny squeeking noises to annoy children and dogs.

Someone figured out a way to use audio to setup a webRTC connection between two nodes.https://github.com/ggerganov/wave-share (h/t hackernews)
