Margaret,
I am not sure that this is really true. When I was looking for a new DSL provider I found that in many cases I could get service at a specific bandwidth with a singe address for about $60 a month. If I wanted a /29 instead, it would cost about $30 more a month. 50% more for 6 usable addresses! I think this is fairly common. The lower cost DSL providers doen't even give the user to choice to get more addresses. People are still being forced to run NAT in response to address scarcity. We could only tell for sure if people would still run NAT for other reasons if addresses were readily available.In my opinion, the only way that we will stop people from using NAT (with or without IPv6 site-local addresses) will be to provider better (architecturally cleaner, more convenient, more functional) mechanisms for people to get the same benefits that they get from NATs today. Although NATs may have started as a response to address space shortage, today their use is driven by the needs for provider-independent addressing and convenient access control. So, we need to work on better ways to provide those things in IPv6.
I ended up finding a different ISP who charged more money, but gave me more bandwidth and the addresses I wanted. Most people would not be willing to do that and would be forced to run NAT.
