I've always figured the easy way to improve adoption rates is to build in a statistical failure to ipv4 stacks; add a kernel option to drop 0.1% of ipv4 packets, or add a 250ms delay to ipv4 packets, and adoption of ipv6 will skyrocket without significantly impacting existing workloads because v4 will still work 99.9% of the time.
