Is three some shell that allows a user to login multiple times to the same session? Id expect to see something like the following, if achieved:
14:16:42 up 9 days, 15:21, 5 users, load average: 0.46, 0.85, 0.94
USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT
jameson tty1 - 14:16 22.00s 0.23s 0.08s -hypothetical_shell_same_PID
jameson tty2 - 14Jul09 9days 5:30m 3.92s -hypothetical_shell_same_PID
jameson pts/0 :0.0 Sun02 4.00s 5.88s 0.95s ssh -hypothetical_shell_same_PID
jameson pts/1 :0.0 13:41 14.00s 0.32s 0.19s ssh -hypothetical_shell_same_PID
Hm... can screen do this?
