This has more than likely been asked already but I was wandering if anyone could tell how to setup a server that has a normal bukkit world and a world with a modpack with a Hub. Here is an example of what I am looking for http://forums.technicpack.net/topic/121538-1710-ohgaming-network-8-different-modpacks-modpack-hub-professionally-operated/ . I mean in the sense that they must have multiple different server jar files installed or have multiple servers with a Hub that lets you connect to the different servers. The reason I want to know is because I want to setup a server with a Hub, at least two different modpacks installed, a bukkit world and possibly a vanilla world too. Is this possible? Also is it possible to have them as different versions of minecraft e.g the modpacks 1.7.10 and the vanilla/bukkit worlds as 1.8?
