For anyone who has a router that allows you to block MAC addresses from accessing the internet, do that. That's what I'm going to do. My Xbox won't be able to get outside of my local network. That way, I can continue to access it with ftp and for relax shares, but I shouldn't have to worry about this new dash coming down the pipe and screwing my software exploits up. I know MS might start forcing a dash update in new games, but I'm sure a quick scan of xbox-scene will alert me to which games are doing it. Hopefully by that time, new soft exploits will have been discovered.
