If the concern is Windows XP, then we can devise specific solutions. Windows XP has some support for IPv6, but also has limitations. Specifically, Windows XP is not designed to run in an IPv6 only environment. For example, it performs name resolution over IPv4, and it has only limited support for IPv6 literal addresses. We can get a list of these limitations, and draft from there the minimal list of IPv4 functions that could be placed in the network to make things work. That could be an interesting project.
