I am afraid not. The real digital divide is between those who can be 
called and those who cannot by lack of money for an IP address (the 
cost of an IPv6 address is also the software change, education, 
missing user tools). This results from an old and costly model (RIRs) 
rather than using a network model (like telephone). This was needed 
in a deployment period, this is a blocking factor for a mature global 
network continuity.

It is a real shame that the entire world has E.164 numbers, with 
billions of people paying them every month, using every days, 
possibly keeping them all their life long, using them for the 
telephone, as customer ID, when they want to be differentiate from 
homonyms in databases, etc. and they cannot use on the  ... modern 
... Internet. By the ITU or by the RIRs, what is the problem to have 
an IPv6 plan made of a leading byte+telephone number?  What is the 
problem of entering a telephone number in a browser and to access the 
corresponding byte+telnr IPv6 address?

In the meanwhile is there an impossibility to think of small 
softwares acting as a local name server and as an external resolver. 
Is there a major problem in having the IP addresses managed 
dynamically (mobile systems would need them anyway)? Is there a big 
problem to get a hook before or after Hosts.txt so anyone can 
organise the responses he wants, for his applications?

I think the real problem is to gather a DNS reference book. So the 
specs, the functions, the tricks of the protocol, the samples of 
existing code are documented authoritatively, a test bed is organised 
and new people with fresh ideas can come, learn and realistically 
develop new projects without being shout at "RFC XXXX!" or start an 
IETF war. mDNS and LLMNR are just that: working ideas. In 22 years 
should we not have had a lot more?

They represent a danger for the DNS? May be, only if the DNS is not 
fool proof or at least resilient enough or embedded in a more global 
system the user has an immediate interest to protect because it would 
affect much more, like in the DRS (distributed registry system I 
alluded to and which seems an interesting area of research). IMHO it 
is in that directions the IETF should work.

Anyway do not worry too much about a DNS network overload, without a 
DRS the langtags support may do better and faster.
