A lot of the potential machines in a VRS would not
have a domain name, at least not one discoverable with
an external DNS. Also, it would require an extra DNS
lookup traffic for every transation

I don't see any problem with the IP numbers being
exposed to administrative nodes. At this point, we
are not worried about anynonimity of the LDS hosts in
a VRS.
