Excellent FAQ, thanks.

A few more things come to mind:

 o What is the minimal distance from Sun at which a (diamondoid?)
   statite can preserve its crystalline structure? Is melting
   point or radiation damage the limiting factor? (In case of a
   red giant it might be possible to sail inside the star for a
   while.)

 o Outgoing radiation doesn't have to have a blackbody spectrum.
   Lasing comes to mind, or one could heat up relatively small
   radiators to a very high temperature.

 o As a matter of fact, outgoing radiation doesn't have to be
   radiation at all, what about gas cooling? A statite close to
   the star could cool itself by accelerating gas from the corona,
   eating away its host.
