Two public lobbies and a staff lobby that /quicklobby never picks. On every lobby, lobbies.conf holds:

lobbies {
  hub-1 {
    fallback-name = "Hub One"
    proxy-name    = "hub1"
    host          = "10.0.0.11"
    port          = 25566
    maximum       = 120
    slot          = 12
    icon          = "GRASS_BLOCK"
    colour        = "0"
    permission    = ""
    weight        = 1.0
  }
  hub-2 {
    fallback-name = "Hub Two"
    proxy-name    = "hub2"
    host          = "10.0.0.12"
    port          = 25566
    maximum       = 120
    slot          = 13
    icon          = "GRASS_BLOCK"
    colour        = "1"
    permission    = ""
    weight        = 1.0
  }
  staff {
    fallback-name = "Staff"
    proxy-name    = "staff"
    host          = "10.0.0.20"
    port          = 25566
    maximum       = 20
    slot          = 14
    icon          = "COMMAND_BLOCK"
    colour        = "good"
    permission    = "server.staff"
    weight        = 0.0
  }
}

1. On hub-1, set this-lobby = "hub-1" in config.conf; on hub-2, "hub-2"; on the staff lobby, "staff".
2. Set status.source = "ping" so a crashed lobby shows offline rather than empty.
3. Name each lobby in every language under lobby.<id>.name in the messages files, or keep the fallback-name.
4. /uxmmultilobby reload on each.
5. Join hub-1 as a player: the compass in slot 4 opens the window, hub-1 glows as "You are here", the staff lobby is locked. /quicklobby sends you to hub-2.

To leave the staff lobby out of the window for players without the node, set menu.hide-locked = true.
