The problem is not in the low-level applications - porting them is doable (http://gsyc.escet.urjc.es/~eva/IPv6-web/ipv6.html http://gsyc.escet.urjc.es/~eva/IPv6-web/ipv6.html) The problem is in the library frameworks that do not give at all the means of making an IPv6 socket. Once that problem is solved - porting the properly written apps is not going to be too difficult. For the IPv4 address literals being scalars - well, properly written programs would have used the DNS names in the first place, and the use of the addresses would be appropriately contained. So I would treat this much as other bugs. Pointers may also fit into int, but it is not a reason to fit them there.
