Here is (hopefully) a "constructive" suggestion. Since IPv6 is going to be the future of the internet it makes sense to try and support it. Obviously thought there is going to be a transition period where support for it is not going to be always available (as is the case at the moment where most home routers do not support it). So would it not make sense for Ubuntu to check for IPv6 connectivity/services either at boot time or as network interfaces go up and down or periodically? If there is IPv6 connectivity/services it should use it otherwise revert to IPv4. That way this problem might be more future proof.
