I would think that server wouldn't last too long mainly because the host won't be able to keep it up after a few days. I would guess this is because of its inconveniences. Keeping a dedicated server requires occasional maintenance--checking on it every now and then to make sure there aren't any problems, such as the server geting unhosted since a serverlist went down or the server suddenly pinging for other players. And not being able to host it because your parents might not want you to could be a big impediment. The longest dedicated server that I can recall is Monolith's Battle Server, but Mono had his share of problems and couldn't keep that server up forever. It was good while it lasted, though.
