1. A method comprising:
- determining a power delivery capability of a system having a power line interface;
detecting a connection of a first device to the power line interface;
negotiating a first power delivery policy with the first device, wherein the negotiating is conducted over a first power line coupled to the power line interface;
updating the power delivery capability of the system based on the first power delivery policy;
detecting a connection of a second device to the power line interface;
negotiating a second power delivery policy with the second device, wherein the negotiating is conducted over a second power line coupled to the power line interface;
updating the power delivery capability of the system based on the second power delivery policy, wherein the first and second power delivery policies each indicate a direction of power delivery.
