So, you're in the "traceroute is not important" camp?
(you'll note that in my email I did ask whether we think 
traceroute is important)

Really?   How?   Remember, we're not talking about RFC1918 space,

We're talking about public IP space, that just doesn't happen to be
announced outside of a particular AS.
