Some "late entries" are/will not be market driven. Some 
companies/organisations could only be searching for a way to become 
independent from their ISPs/suppliers, and the only way they can do that 
(IPv4-wise) is to become a LIR and get their own chunk. I also hope that 
by doing so, they will also be flooded with information about IPv6.

A flag day won't work. There are simply too many networks.

Yes, that's the main point. People use what they know it works, and they 
need to be comfortable about what they are using/managing.
If all networks in the world were run by 10 or 100 people, then yes, an 
agreed change would be possible. However, that's not the case, so 
co-existence for a long period is unavoidable.

Yes, people should be using IPv6 unknowingly (in a transparent way), but 
it's useful that network managers and sysadmins know about it :-)

That's everyone's case, i'm afraid :-))

I've been deploying and advocating IPv6 since 2001. Others have been doing 
it for a longer period. Within this timespan, i have only read about *one* 
organisation which publicly expressed plans to scrap IPv4 from their 
network/services, but they have dropped that in the meanwhile...

IPv6 will not happen by decree, it is happenning, slowly, due to need and 
a vision for Internet's growth (imho).


Best Regards,
Carlos
