Imagine a two stage vehicle, one with a large ring, one with a smaller one that can expand and perhaps use unspent exotic matter, assuming it dimishes in mass in the trip. I would think that something has to be given up. Now maybe I'm thinking too much about rocketry to assuming what FTL engineering is like--but I would think there would have to be a trade off. The key is that you want to build a base, and perhaps leave exotic matter in the football and live in the ring if you are left behind--then have some form of entanglement.
Imagine this. A two stage ring ship heads out, one ring remains. The exotic matter is reconfigured to the center of the ring station for another purpose--perhaps teleportation. If that doesn't work, return on the ring ship pod.
I don't know why I think this, but I think there is going to be some type of articulated design in warp drives in some sense. Just a hunch mind you.
