variable viscosity?

[super gnu]

is it possible (even theoretically) to use a 3d map to control viscosity or other properties of a fluid? ive filled a volume with fluid and id love it if i could get a mix of thick and thin parts.

of course how they would interact could get complicated.. do they stay seperate or gradually mix together into one medium viscosity soup?

technically is not a problem, but currently there is no such option.
