I am wondering, since we are dealing with micron sized particles,
whether you could actually have a sperical cloud rather than a dust
ring without lots of collisions of particles. I am wondering if
electrostatic repulsion would be sufficient at those scales to prevent
actual collisions and instead replicate a form of brownian motion.
Theoretically, by living off of solar energy, such particles could
avoid loss of momentum that such motion would cause.

This would also create an electrostatic bottle effect on solar wind,
which would help keep the sphere inflated.
