In a large bowl, sprinkle gelatine over cold water; let stand 5 minutes to soften. Add sugar and boiling water; stir until sugar and gelatine are dissolved. Stir in strawberries and beverage concentrate. Stir until strawberries are separated and partially thawed. Chill until partially set.
When gelatine is ready, whip cream until soft peaks form. With same beaters, beat together cream cheese, powdered sugar and vanilla extract in a small bowl until smooth. Fold in whipped cream. Alternately spoon mounds of cream cheese mixture and gelatine mixture into pie crust. Run a knife or spatula through mixture to get marbled effect. Chill 3 to 4 hours or until set.
