Eternal Terminal (ET) is a remote shell that automatically reconnects without interrupting the session. A layer in between an application and unix TCP sockets that make the sockets robust to TCP disconnects including roaming and connection failure. Implements some of the tmux user experience, even works with the tmux control center (tmux -CC). Buffers bytes written and read so they can be replayed in the event of a disconnection. Starts with SSH to make the initial connection and authentication. After that, it uses its own encrypted network protocol.
Text mode window environment. A "retro" program for embedded or remote systems, that doubles as X11 terminal and text-mode equivalent of VNC server. It's a serious oversimplification, but think text-mode X, or maybe something like Desqview for DOS. Mouse support, window manager, terminal emulator and networked clients, all inside a text display.
