nope, if you start a map you become a "seed" or "someone with all the info." if I join you I become a "peer" and all the info that you have is sent to me and then I become a seed. As long as there is at least one seed, new logins will be possible. If all people shut off their program, the first to reopen the map will become the first seed, starting the process all over again. if you make it central to the map maker, but if the map maker is on a slow internet, EVERYONE on that map will be slow. In addition, the more people who login to a central map, the slower that person's internet will be. If there is one seed and many peers, it will take a relatively long time to spread the info around. On the other hand, if there is a lot of seeds, then it will go fast. Seeds are like servers and peers are like users, if you have one server(seed) and 1000 users(peer), you need a server that can handle that. If you have 1000 servers(seed) and 1 user(peer)... you get the idea.
