Well, yes and no. I agree that we should seek to avoid an
explosion of top level naming authorities, and we
certainly shouldn't all seek to be our own authority, but
I see nothing wrong with having a distributed name space,
which allows the delegation of authority a la DNS.

Thus, you might find something like

URN:ISOC/europe:user=4321102:12032:::

This would translate as an Internet Society user ID, which
was granted by their european server. I just made this up
on the spot, so don't worry about specific syntax, but I
think the idea of having distributed authorities will be
important as we continue to run the "numbers connected"
counter off the scale.
