Outside purposes of testing by power users, doubtful.

But I assume there will be in the future (which is 
inevitable, due to the guaranteed rising costs of 
maintaining an IPv4 Internet), so I build out on that basis.

Agree.

And this is going to impact mobile providers, the world 
over, who are spending more time investing in NAT44 than 
IPv6.

I think we have seen a bunch of operators running Cisco 
6500's/7600's that are struggling to keep up, in recent 
weeks - and this platform has had known issues for scaling 
its FIB for a while now.

This will only get worse.
