I am told by people who have inside knowledge that one of the issues
they are facing in deploying IPv6 is that an IPv6 stack + IPv4 stack
have a larger memory footprint that IPv4 alone in devices that have
essentially zero memory for code left (in fact, they're designed that
way). Fixing devices so that they can accept 240/4 is a software fix
that can be done with a binary patch and no additional memory. And
there are a _lot_ of these devices.
