How "particle-like" are photons? Is it possible to create a spin, like a billiard ball? If so, can a spinning photon (or electron etc.) be made to fit a curved path through a medium? I'm not sure whether or not a spinning mass is relevant in a vacuum with respect to direction.
Should spin be imparted onto a photon or electron, does this lend itself to applications where a particle source can be aimed to multiple locations through spin alone? This could lead to new micro-switches with higher processing speeds and less (if any) moving parts to achieve path differentiation.

Black Holes
When Black Holes evaporate and leak Hawking radiation, do they maintain the density of mass to remain Black Holes, or do they lose the critical mass at some point and self-destruct back into the "normal universe" - that is, no longer form a singularity?
If so, does this assist with the problem of information loss? The current theories seem to assume that Black Holes remain Black Holes until the final atom evaporates and it disappears. Could not the remnants of a Black Hole be a substantial mass that remains when the total Black Hole mass drops below the threshold that requires a greater than C escape velocity?
