How about an additional type of warp-point generator that requires a component/ facility at BOTH ends of the connection? For long-range warp points, you'd need to control both systems because you'd be required to build some massive starbase at either end. For short range ones you could use the existing method, with a ship at one just one end carrying the warp point opener we are familiar with.

This could really help balance stellar manipulation by making it harder to just warp into the heart of your enemy's territory and create havoc.
Oh, and allow stellar manip to be used by bases=-)
