Sorry for taking so long to get back on this - it's an important point 
you make.

I like IPv6.  In fact this Wednesday my company is doing a technical 
seminar on the current state, and practical use of, network management 
tools in v6 networks.

But I don't see the driving force to compel IPv6.  Yes, V4 addresses are 
getting scarcer.

But for each of those 1000+ nets that you say are announcing v6 prefixes 
- how many are doing *only* v6 prefixes and not also announcing v4 
prefixes that lead to exactly the same computers?

In other words, I don't see new users adopting v6 alone.  These new 
users will need to talk to the vast legacy world of v4 machines. 
Consequently users of of v6 will find it necessary to also run v4.

In other words, I see two parallel paths for IPv6 to grow:

    - Legacy users of IPv4 who add IPv6 capabilities.  These people will 
retain IPv4 so they can continue to talk to the existing IPv4 world. 
This will put no strain on the existing IPv4 pool.

    - New users who chose to use IPv6.  These people will need to 
acquire IPv4 capabilities so that they can talk to the existing IPv4 
world.  These latter users will tend to require, block for block, an 
IPv4 allocation for every IPv6 allocation.  And I suspect it would be 
unusual for sites to go public space for IPv6 but private, NAT'ed space 
for IPv4.

The root of the problem, as I perceive it, is that IPv6 and IPv4 create 
parallel but disjoint internets.  Connectivity between them will be via 
a relatively few application level gateways (ALGs) - email relays, web 
proxies, SIP (VoIP) proxies and call gateways, etc.

 From the point of view of internet governance, these interconnection 
points become internet versions of the Panama, Suez, and the Straits of 
Malacca - points through which control can be multiplied.  (Yes, people 
can deploy new ALGs between the v4 and v6 worlds, which does diminish my 
analogy somewhat.)

Have fun in Rio!
