greetings

Just a thought; i do this with my ssh connections

do shell script " whoami "
root

scan ps -aux for the tty or process and it will list the user  
connections.

ps -aux | grep ssh

root     10310   0.0 -0.1    30316   1100  ??  S    11:46AM   0:00.08 / 
usr/sbin/sshd -i


another is as the user ps the user processes.
example.
nc1-100:~ drfoo$ ps
   PID TTY           TIME CMD
15450 ttys000    0:00.01 -bash
15459 ttys001    0:00.01 -bash
15504 ttys001    0:00.39 ssh -l root mail2

or something like that.

man ps for more ideas.
