Yes we all go to NANOG meetings and talk about these solutions but the change has to come from within. its not just a technical solution. There has to be motivation and incentive for people to make this change.

Just upgrade your load balancer (or request a feature from your load 
balancer company) to map an external IPv6 address to a pool of IPv4 
servers. Problem solved.

Continue to run IPv4 internally for this application. There's no logical 
reason that IPv4 can't continue to coexist for decades. Heck, people 
still run IPX, right?
