would be interested in reading that .. do you happen to have a link?
but i do not think this could be too close ..
and it needs to fit to the signal turnaround time of several seconds, so
it cannot be too close ..

yep . light pressure is dependent on the angle of the mirror, so the
direction of its force can be adjusdted - the pressure from solar wind
is independent from mirrir angle and always points directly outward
(unless we start to add curlicues like a magnetic sail on the soletta)

its the simplest solution imho .. occam's razor
