I love (ab)using protocols that are built-in to most OS'. I wrote a dumb fake samba share that let people see messages in Finder.app/Explorer.exe/Gnome/KDE since I couldn't find a cross-platform gui or cli messaging system that didn't require installing special client software. (even netcat invocations were not working when trying on our local network, and had OS-specific flag differences if we wanted to do broadcast). You see the samba share message in your file browser, click it and can edit the filenames to update a 3-line "bulletin board". https://github.com/jedahan/samba-haiku/blob/master/index.js https://github.com/jedahan/samba-haiku/blob/master/index.js Even this was a re-implementation that used WIFI ssids to make a captive portal haiku. https://github.com/jedahan/haiku-wifi https://github.com/jedahan/haiku-wifi
