Build the water surface so it is a multi-faceted square, just inside the inner part of 
the glass. Apply a b/w clip map of a full black circle on a white background to the 
water. 

The circle must accurately touch the border of the clip map. Apply it planarly and 
turn on 'World Coordinates'. 

Unless you move the water (alone or as part of the glass hierarchy) you can apply any 
displacement mapping to it and it would fit perfectly in the glass.

.Unless I miss the point completely, as someone here put it.
