Hello,
I find this thread more and more interesting, as it can lead to a very
large understanding about many aspects of what root priviledges can lead to.
However, nobody talked yet about the interest of having additionnally
a Superuser Terminal in the Applications/System menu. And the fact that
to log in this terminal, the first user password is required. (I call 
first user the one who installed, and masters his system)
I think we have truely plenty possibilities.
What do you think about it ? is this second terminal useful in any way ?
Otherwise, I think sudo is very good for newbies, and should even 
natively configured to 0 time before reentering the password. I've also 
already seen twice some newbie 'special command line' with a '#sudo 
whatever' and had never seen the same elsewere :)
