I see the opposite on my machine.  Admin window has empty $SESSIONNAME, non-Admin 
window has "Console".

What I do locally is check the output of the 'id' command.  If group 
544(Administrators) is present, that's a window with Admin rights.  Inside .bashrc 
I have a simple grep test on the output of 'id' to set PS1 (shell prompt) 
appropriately.
