[Portable Teleportation Device]
Teleportation Network
Simple idea, but might be harder to implement.
Teleporters wich will be capable of locking on to a frequency, (1-9999) and maybe password encoded so people can't just join every frequency.
For every Teleporter connected to a fequency, there will be a button, with a max of 10 teleporters on 1 frequency, also, each teleporter can be named.
