To the extent that you don't call that a criminal aberration -- one
that could as easily have happened to one of the root servers currently
*taking* the ICANN root zone -- it only affected people who were
resolving off that root.  That's a pretty small number, and, IMHO,
doesn't rise to the level of "placing the infrastructure [of the entire
net] at risk".

And that possibility is any different in the n-root case than in the
1-root case... why?
