Interesting to think about:

  * How much mass could be positioned at L1 before changing the gravitational proposition of L1?
  * How large an object could be positioned at L1 before it exceeded the practical bounds of L1?
  * Presumably the object would reflect rather than absorb solar radiation. How would it deal with other solar ejecta?
