Xbox Live can't be broken into like PSN was. J-Tagging doesn't modify Xbox Live, just your console. THERE are exploits on Xbox Live like the most recent Gears 3 beta download but those people are banned from the game when it comes out. Honestly, I can't see LIVE getting hacked into, it's not accessible like PSN is, aside from the Marketplace and whatnot.
