Well the latest info from a few days ago from Crediar says it's possible, he has access to all hardware while playing GC games. This doesn't mean wifi GC network loading is anywhere near a release. He would still need to patch the network access to use wifi, which is as complicated or even more complicated than replacing dvd read calls with usb read calls. I don't think he is working on it, and the chance he will release it so that other devs might be able to do it is nothing i would count on.
