Yeah, I know it's not possible to use a hdd to play games without jtag, at least not the way it's possible on the original Xbox or the Wii. What I'm wondering is: how come? With the recent discovery of the PS3-keys everything seems possible, swo in a way it's remarkable that there hasn't been such an feature for the 360. What's the obstacle that keeps us from using a hdd, or running homebrew? Is Microsoft's protection really that much better than Ninty's or Sony's?
