The idea. It would function as a walkway block that way you would have dedicated lines to critical systems.
You would have someone in the reactor load a power cell into the adjacent connector and a second crew man take it from the other end and pop it where it needs to go.
The benifit. Lower crew logistics requirements due to travel times.
The challenge. The power line blocks would be something akin to the railgun as in you cannot traverse through them.
If used creatively it could segment ships along with opening the potential for 'automation circuts' such as a detector that automatically turns systems off when not in combat or in an ion cloud. Automation means less micromanagement if you can pull it off properly. Which might open a whole new field of engineering complexity in the game.
