ok, you know how you startup wow, and they do it on the launch page, or when you try to login, since the realmlist.wtf is set to there host and they stream you the data?
well if you are on your own realmlist.wtf/private server, whats the possibility of being able to stream your own updates, and beggining to add your own models or textures, rather than following blizzards every step X D
