I just wanted to draw attention to this, in the URN paper, and the scheme
being used in the test-bed , we dont use the centroids or
Directory-of-servers to find the correct servers, because both it is too
slow especially if its working over thousands of servers. It is probably
appropriate for a directory search, but not for a resolution of a URN.
