I remember encountering this project: https://piratebox.cc/faq , I even still have a compatible hardware at home.
I wonder if allowing it to have instant messaging (including offline asynchronous messaging) would change how people in a small community communicate each other. I wonder if, for one, it would induce Internet trolling.
I have one of these, not in operation but could deploy by just plugging into power and attaching it to a higher gain antenna. It does have a message-baord type function included, but it's anonymous and there's no sign-in so there's also no way to administer it or edit / delete your own messages (piratebox is a product of a more innocent age, maybe). It's also possible to upload files to it, anonymously.
Both of these things make me worry about liability in the event of the type of jerks where the term "jerk" is possibly the nicest way to describe the person.
(I have it on a GL.Inet Mango device and it took me a lot of digging to find the install binaries and instructions, and I don't even know if said binaries and instructions specific to the Mango exist anymore - I don't have the time / energy / motivation to try to dig it up again, I remember there were lots of trails that led to almost the right information)
