The dot info and dot biz rollout IS a "Proof-of-Concept"
to see if further TLDs are needed....Image Online Design built it's "Proof-of-Concept"
registry for that reason (and to provide competition )...For all practical purposes,
the "dot com" database is a "Proof-of-Concept" registry (very loose usage of "Proof-of-Concept
here, but in fact it is just that)...Proof-of-concept doesn't mean you will lose
your domain names...It's "tech" terminology for: Let's see what works, and
what doesn't with this rollout...
NOW TO PUT TO REST ANY FEARS: The difference
between Jim Fleming's use of "Proof-of-Concept" is that there has to be some kind
of official recognition by a ruling body...IN this case ICANN approved the dot info
and dot biz "Proof-of-Concept" rollout....IANA approved Image Online Design's dot
web registry...I believe the US gov't approved NSI's dot com "proof-of-concept (don't
quote me on that, but obviously the US gov't kicked things off)....
Jim Fleming's
dot-biz is not a "proof-of-concept" registry for that last reason: Official
recognition....And now that the Neulevel dot biz is officially in the pipeline...well..I
am not sure what it is...
Hope that answers your question...If not I am sure Jim
will try to do it for me! (LOL)
