    Just curious - how large is L2?  Is it just one precise point, is it
    multi-km ^ 3 ?  If you're going to fit 10 spacecraft at L2, I would think
    that L2 would be at least 100 km ^ 3 (if it's smaller than that, then
    you're going to have a risk of collision that will be greater than
    intentional ignorance).
    Just to be sure - we're talking about L2 in the Sun - Earth system,
