What are some user friendly LAN text messengers for mobile/PC?
Not really from a privacy concern, that's simply a bonus, more of a reliability/convenience interest. Even if internet/mobile internet is out for some reason, being able to easily text across local network would be nice.
For Windows/Android mainly, but crossplatform tools that include those are great too!
On Windows (NT?) you used to be able to send a message across the LAN which would just pop up in a message box. Can't remember the command. Probably doesn't work anymore anyway.
