How long does it take an ISP or mobile carrier to roll out IPv6?  My 
experience was seven years, but 4-5 years may be more realistic now. Has 
anyone done it in two?

We are now in Exhaustion Phase 1, right? Suppose soft-landing-bis is 
adopted.
If a company is providing Internet service (landline) to more than 
16,000 new users every two years, they will exceed their maximum /18 
allocation before they will have been able to deploy IPv6.
What will they do then?
1. They can do IPv6+ IPv4aaS. But they haven't had time to roll out IPv6.
2. They can buy more IPv4 addresses. However, Afrinic will only allow 
transfers from existing African address holders. Will there be sellers? 
If so, and the cost of addresses is passed on to consumers, will they be 
able to afford service?
3. They can deploy CGN/NAT44.

If they do #3, will they also do #1? Or will they decide it's good 
enough and stay on IPv4+NAT?

Right now, that only applies to large companies adding 8,000 users per year.
If this policy is adopted, the same line of questions applies to any 
company growing by more than 500 users per year. When will we reach 
Exhaustion Phase 2? Is there enough time to deploy IPv6 before running 
out of addresses in Phase 2?

Mobile carriers already do CGN. I don't know the ratio of customers to 
address. The same questions still apply, just at different multiples.
