@shams,
I rechecked my code, and it says it is what I have posted, so maybe they haven't gotten the server connected to the other servers internationally yet. Would explain why I can't get either of yours to work, but you can connect to each other.
Edit: The Nintendo of US wifi page still only shows Pokemon Battle Revolution for Wi-Fi Wii games, so this may add a little evidence to that possibility.
Edit2: Parts of the site has it.
