Does anyone know if Fry's Coco in Canada is GF?  and what about carnation's
powdered milk...  If these two things are found to be gluten free, one could
make a hot chocolate mix by throwing all of the dry ingredients into a food
processor.  Coco, Granulated sugar, powdered milk...  and let it all spin at
high speed for about 5-10 minutes, it should become fine dust just as
commercial hot chocholate mix does...
 
Just a thought!
