asterisk users - Oct 2008 - a question about linux/asterisk/commands

hi;
I'm curious, is there a way, after i set up an admin ivr one needs a  
password to enter, to make for say
option 7
for say give me current bandwith usage information? Let me tell you  
what i do now and you could give me your ideas.
First of all i have a user, mbabcock that i ssh with, I'm using the  
latest of freepbx and right now how i get the status for me is typing  
vnstat and getting resolts like this:
$ vnstat
