Not bad. It works quite well. It doesn't take long to start up a survival world for your friends. The online console could use some work though. It is a bit of an effort to edit your server files and having different color schemes to choose from would be nice. As weird as this sounds, you could say this server is the server of servers. It may be the ultimate server. It will take some time for a decent sized player base to form, but if you market this right then it will probably take less than a couple months. I think the best way to get a lot of players in a very short period of time is to make it easy to create modded servers. You can probably cut down the growing cost with well placed advertisements and offering payment plans that increase the amount of memory a server is allocated for example. You have an early competitive advantage of not requiring server owners to pay for plugins. That might not be sustainable later on though.
