OK so we now know that the Wii has a decent web browser built in so what's their excuse for charging 500 points to add an address bar and forward/back buttons?! Disgraceful profiteering.
TBH while I'm happy that someone has figured this out as a 2-fingers to Nintendo, I wouldn't be arsed and will just load up Firefox on my PC any time I need it.
Now if someone could port Firefox or another OS browser to Wii, that would be impressive.
EDIT: PS I don't think it would be practical for Nintendo to brick your Wii for doing this. As the video shows, you can just change the settings back anyway. All your actually doing is changing the server that the Wii gets address (DNS) details from.
