screen is an excellent program which lets you have
multiple virtual terminals in one ssh/telnet session. Hotkeys let you
toggle between the virtual terminals. Best of all, you can leave the
session running, log out, and then reconnect later. You can leave
emacs running in one of the virtual terminals. Then its buffers and
history are intact when you next log in.
VNC is a pair of programs, one of which shares a desktop

desktop on another machine. On a GNU/Linux machine, run
vncserver to start a new VNC desktop and use
vncviewer to connect to an existing desktop. In recent
distributions, you can share your current desktop using
