Manycast uses Autokey or Symmetric Keys unless authentication is
explicitly disabled. In this example Symmetric Keys will be used.

Manycasting uses network broadcast or multicast addresses for server
detection. While this is trivial on a LAN or WAN, manycasting over the
Internet will require ubquitous multicast support.
