Getting that game on your diskless console is where things get interesting. For some titles, you might be able to download a digital version of the game from Game Pass or stream it from Xbox Cloud Gaming, but not all titles will be available. In those cases, Microsoft envisions a system for "streaming and/or downloading content from local network devices." So, one device would stream the game to another, saving you a ton of internet bandwidth. This would be a fantastic standalone feature.
Microsoft also acknowledges in the patent that such a system could address the increasing prevalence of diskless game consoles. It would have been unthinkable to ditch the discs in previous generations, but there may come a time in the near future when there's no optical drive option at all. People who have large libraries of games, either because they like collecting them or just prefer local media for technical reasons, should not miss out on great gaming experiences. Whether or not Microsoft will follow through and turn this into a real service is impossible to say, but this could be a selling point over Sony's consoles.
