I'm not sure it will be that only because the Defenders have beds which weakens the parasite ship theory as well as the remote control theory. It is designed to be long term fighter support (notice I did not say long distance). My money is still on some kind of contact-less connection. Sensor linking, regenerating hull when in range, fuel replenishing, or shield boosting Like beaming energy to the Defender so when its in range it's shields recover faster/stronger (A.K.A. AoE defense boost from the BMM). The Banu seem to favor shields over armor so the last one is my top theory.
