The cool part about this is that mobile network operators can potentially move their networks to IPv6-only and still support applications like Skype that are still IPv4-only. Yes, this was a demo of pre-production code, so it has to get out there into the actual devices. And the code was only for Android, so it needs to be for other devices, too. So yes, this is not a solution that will happen today, but is shows the path for how a solution can be found to let operators move their networks to IPv6 even if app vendors aren't ready/willing to make the move.
