@ftg @n6cta When I think of large message store and forward, I think of PACTOR and the Winlink system. I wonder if a ham FIDONET could be built on a similar stack. Framing long messages on a weak signal format designed for short and ephemeral band openings just feels like a square peg in a round hole. For keyboard chats it's fine but anything larger feels like it's pushing it.
I wasa FIDONET kid, and I can confirm it felt magic at the time.
