Many folks have requested this in the past. They wanted to have ethernet on the car connector, but couldn't do it because there wasn't a such thing as a reliable car docking connector with enough pins.

Note that the docking cage has a gap around these connectors, for the sole purpose of being able to reach the plugs in the docking cage. Some people have creatively fashioned their own ethernet connections for the docking cage. It can be done if you are careful about the mounting.
