So this seems super-interesting and significant as a potential extra-terrestrial life target: The structure of that solar system is more like a gas-giant/moon relationship like Jupiter and its moons. If the system is really planet-rich and they have orbital resonance relationships with each other, that means they could have tides, and this could also help keep the planets internally molten, and thus have protective magnetic fields.
