Actually, I think that it might be interesting to look at the possibility
of putting Root DNS on the Route-Servers.

Interesting... That should definitely help.

True.  However, the nice thing about a RNS on an XP is that the RNS is one
hop from EVERY provider at the XP, and is independent of OTHER providers.
I agree that the XP management shouldn't manage the RNS.  However, I would
be QUITE comfortable with MERIT running it on the RS or adjacent machine.

Although I agree that ALL RNS's shouldn't be run by a single organization, I would
not have a problem with the RNS's at the XP's being run by the RADB group.
