Yes, these systems are specifically tailored to the server they are made for -- but there has been no public release from anyone about how it's done; even the very basics have been unrevealed. That's what is the worst part (for me) so far. There's no word from anyone on how to even start, so many developers are left in the dark... And for server owners like myself with little Java knowledge and not-so-full pockets, no developer means no plugin. That's what the big hype (at least I'm excited) has been about LegendaryCraft releasing a system. Obviously, it won't be as easy as typing the IP addresses into a config, but at least it's somewhere to start.
