Besides few loose nuts out there that have been trying to do the same
thing for two decades, there is no real incentive (meaning money) for
a $7B+ industry to change its ecosystem and pay attention to another
troll.

The technology to have/use an alternate dns root exists and is
available to anybody, you just need to convince couple of hundred
million users and service providers to point to your own servers, and
then we can make a movie about the fights that will surface when
people try to determine who runs the servers and how and who/how you
pay to keep it running.

Again, what we need is something better and more elaborated that an
alternate root, a new scheme that enables applications to locate
resources using a protocol and name space that is not tied to the
current DNS.
