Nonsense. BCP32 (RFC 2606) specifically alters a root zone by adding 
reserved TLDs. How many combinations of the root does that provide for? And 
RFC2826 has been clarified here on the Nanog list as "one root at a time" 
and not mixing multiple roots. OK by me, but at some point sanity should 
prevail and that running code and rough consensus demands the peering of 
non-conflicting TLDs for everyone's benefit. It's a common practise in 
other spaces, so why not in the DNS space? I don't understand the "my way 
or the highway" mentality.

Nonsense. I've not used the legacy root since I proposed the shared-TLD 
model (and explained it to Postel) back in 1995/6 (FYI, the last version of 
the Internet Draft is at the IAHC website). Everytime Verisign/NSI screws 
up the .COM glue I don't notice a thing. Something to be said for that. At 
least one ICANN board member recognizes the limitations under 
ROOT-SERVERS.NET and chooses another root for service. I don't blame 'em.

F.ROOT-SERVERS.NET is a "value subtraction service". It misses published 
portions of the name space - so if you use it, it is of limited value. I 
can reach twice as many TLDs elsewhere. Oh yeah. It's "stable". I forgot.

What ticks me off is the zero-sum game being played. Anyone saying "there 
can only be one root zone" and supporting a closed and non-inclusive root 
is playing a zero sum game. "We win, you lose" is not the spirit of the 
internet, running code and rough-consensus.
