The Nintendo Wii uses wireless G so it is possible to stream video games from another computer off your network. To stream a video game to the Wii you need to create a shell for the game to run off of a computer, then use a modified Homebrew application to run the visuals off of the Wii. While people have programmed an application for the Nintendo GameCube for this exact purpose, it has not been modified to run off of the Nintendo Wii yet. If you have the programming skills, you can tweak the GameCube application to run off the Wii.
