Dynamic Network
One of the most exciting use cases of FTA is the ability to dynamically link gates on-demand. Instead of requiring a pair of gates for every system you might want to jump to from your home system, one central gate could connect to another central gate in any of those systems. This would also allow on-demand offlining/onlining of gates and network nodes to save fuel costs.
Currently, linking gates can only be done in-game as a sponsored transaction (gate::link_gates()), but CCP has confirmed that they are investigating whether this can be made a dynamic, automated operation.
This system would also allow builders to register a single gate with FTA instead of a linked pair of gates, reducing the cost of entry into the FTA.
