Am I the only one that thought of this?

That is a cool idea but like D said, Nintendo would think it to be to risky. As far as how long it would last with battery, it would depend. The WaveBird uses 2 AA batterys and last up to 100 hours. A wireless keyboard on the other hand, would be a completly diffrent story. I would guess that they wouldn't use AA, more like D's or a chager included.
