The plugin, "VanishNoPacket", is a very common plugin on huge survival servers. It allows admins to vanish in an "unhackable" way because it stops the server from broadcasting update packets to users. I know that with the current API it is not possible to do so, so what I'm suggesting is exporting something like packet broadcasting to the API.
