Is it possible to make a plugin that creates portals that will travel to a different server? I know this sounds far fetched but it would be nice to have.
Bungeecord is fully documented on spiggotmc.org, which is a fork of bukkit I believe made by md_5, but Bungee may be compatible for bukkit, but I think all bukkit plugins work on spiggot, but I would need confirmation.
