Yes, but only for very simple DC power. There's no data communications going on.
Ifg you need 5 meters of range, get a wireless wii sensor bar (either homemade mod or 3rd party) and move the sensor bar closer to where you're sitting. It should work just as well as if it was close up to the TV as you don't actually aim directly at stuff on the TV image when you aim with the wiimote..
The one tested on ign is UGLY! I won't put one in my livingroom, also putting the sensor bar closer is out of the question, as there is nothing but floor and a heavy glass coffee table between the screen and sofa, and I won't be putting it on the coffee table because ithe sensor bar would have to be moved away when not gaming. I want my livingroom to stay nice and tidy, and moving things around when I feel like playing is too much hassle.
Seems like no Wii for me, yet. Until there's some neater third party wireless sensor bar available, or a ready-made extension cord.
Well, I can't find a Wii anyway anywhere yet, so with luck once there's more units available there'd also pe other solutions for the bundled sensor bar.
It's just that I really don't like getting some third party, not officially endorsed gear to replace an nintendo made one the same day I get the console.
Funny, it was a similar reason I never got to buy a Game Cube. It just didn't fit in my entertainment centre without making same (possibly) quality degrading compromises. The S-video was disabled on the EU console, and at that time it and composhite would have been the only possible options for me to make the GC fit in witout either sacrificing the only RGB SCART on my telly for GC (I rather used it for DVD), or buying a SCART switch, which I was reluctant to do because of possible degrading of the DVD image.
