Need to fill unique values for inter-contour area between each contour 
(was thinking of vector color fill and subsequent saving as raster where 
could be assigned unique category values)

Can you elaborate a bit on how to use r.grow.distance for this
purpose. My input map would be a contour raster map.

Yes, I tried several of the interpolation options, but our data is huge and
interpolation takes a long time (r.surf.contour has been running for 
several days
now), so we are looking for a simple unique value fill solution that 
could work
