We are not specifically interested in the way servers call 
themselves. We are interested in servers where IUsers can find 
identified information on the top zone. Identified information means 
that the information collection and dissemination policy are 
reasonably documented, consistent and stable. And made plainly 
available to the IUsers.

You may have noted that this is my organisation.You are free t to 
access our under development site: http://vgnics.net. I accept that 
the VGNIC concept fosters competition (cf. ICANN by-laws) in the name 
space and that you may wish to comment it. Your experience as a the 
largest so far VGNIC manager could be precious to the community.

However, I must say that due to our limited resources we focus on the 
EZOP (exploration of the primary zone map) and the subsequent 
HomeRoot experimentation project. My "rootservers" list isthe 
preparation of an input to EZOP. ORSN documents the IPs of all its 
machines, not the RSSAC. This might be embarrassing in case of 
necessity and/or local limited access (islands, earth breaks, wars, 
social events, power shortages, tsunamis, etc.) or update/political 

Steve Crocker's remark about access surety and delays to TLD's name 
server is of the essence. However, rather than being business 
oriented like ICANNers advocating .com TNCs registry duplication 
(they might afford the cost) we are interested in supporting free 
registration for local emergency services. Local replication of the 
national TLD name servers, as well.  We documented that we will want 
to support HomeRoot TTLs as TTRs, i.e. "time to resurect" if access 
to the TLD nameserver was not possible.

Thank you for this information. That is far more precise than the 
"earth" entry by the ROOT-B manager. This increase the number of US 
located top zone name servers to 70.

Correct. Hence the VGNICS criteria about information collection and 
dissemination policy being reasonably documented, consistent and 
stable, and made plainly available to IUsers.
