For the hosting providers then fun really starts when you can't get a public IPv4 for your new webserver, that'll be fun. There's no NAT workaround for that, some european hosting providers are already feeling the crunch in their IPv4 blocks, you can only host so many servers. So what can you do? Jack up the prices ofcourse, isn't the free market wonderful!
This. This is why IPv4 will stick around for decades to come. There is too much profit potential in it, and IPv6 costs too much money to implement.
