Sad IPv4 story?

I really didn't follow to much of this thread, it's all a bit weird with 
some obvious industry under currents running that I don't follow.

What I will say is that I'm currently involved with exactly this issue 
and would have to say that it's all just getting sillier by the day.

I've been researching solutions with NAT and double NAT in mind because 
it's obvious that v4 space is going to become a growing problem.

It's interesting to see the things that break when you use double NAT.

What's also interesting is the growing competitive market place with 
incumbent providers, who have enough v4 space for their entire market, 
contracting their retail operations while their retail competitors are 
growing in size.

I've been working on some very basic projections for my country and 
expect over the next decade we will see at least 30%, or more, movement 
in our market.

So where is this going to leave v4 allocations?  Will the incumbents 
protect their retail operations by locking up their v4 space so that 
smaller competitors can't grow?

Will we all move to v6 to make the problem go away?  (Not likely, the 
level of edge understanding of v6 isn't there, and you lot already had a 
rant about CPE this week, so I won't go there!)

Will we develop smarter v4 technology and just NAT on NAT... and on NAT?

The only thing that is really clear is the lack of clarity.
