That’s not what he means. The original minecraft_server.jar has an option to launch as a gui console rather than the normal console. It’s the same thing than the console but it shows CPU, RAM usage, etc.
No, it will not implement the minecraft_server.jar source because of all that legal stuff with Bukkit, I mean the server should have a similar GUI that the minecraft_server.jar has instead of a Cmd/Terminal Window it could have its own window that looks like this:
With the new logger all the classes that use System.out.println("Loading properties"); will use their class name as identifier. Also their is no reason for Sponge to change that name, because sponge isn’t loading the config file, Minecraft is doing that .
As long as it doesn’t intefear with hosting an actual website on the server box port 80, maybe even just a php page to add to an existing website hosted on the same box.
This: http://www.mcmyadmin.com/ seams to be a peace of software, I was thinking just a php or even html with java script page that can be added to any web hosting program running on the same box. Perhapse even as a hiden/passworded page added to your existing servers website.
