[ExI] The Great Silence again

[Anders Sandberg]

One problem I see with our starmoving scheme is keeping the Dyson cloud 
in orbit. When it reflects the star's light it will also tend to 
expand/move ahead, and we need to restore it to it's original position 
relative to the star. That seems to require some work.

A statite will be kept in place by gravity, but that only works for a 
ring around the star, not a whole shell. Is there any analysis of closed 
static orbits for reflectors reflecting in a particular direction?
