A thing to watch out for is that the surfaces of the fluid and the glass will never completely match (even if you use the same faces) so this only works if you make sure there is a slight gap between the fluid and the glass, otherwise you get rather obvious artifacts. Luxrender also doesn't keep track of the index of reflection the way you'd expect. The only way to make it look completely right is to have a 'boundary between glass and fluid' material for which you calculate the IOR manually. Nice tutorial.
