The official client is an emacs package, interesting! These parts from the readme made me chuckle:

I'm getting all my friends into Meshtastic, a system of mesh networked packet radios that can be very cheap and do not require a HAM license.

A few of us will be trying out then forking a BBS running on an RPi connected to a radio node. Though that will technically be less decentralized, it will be more social media like.
