Then maybe it (data transfer) could have a use in deployable rovers that have no innate science capacity. Similar to how the curiosity rover acquires data but does little processing on its own, small range communication between rovers with science instruments and orbiting science-lab laden craft could get around the energy requirements necessary for a science-lab lander. Not having to load a lander with a science lab, a brayton cycle turbine, and a large nuclear reactor would make gathering data off of the surface of a body much simpler and more survivable (recoverable) in cases such as Eve.
