Sprinkle gelatin over cold water in mixing bowl; set aside 10 minutes to soften. Add boiling water and stir to completely dissolve. (If gelatin does not dissolve completely, heat slightly.) Set aside. Combine blueberries, lemon juice and sugar replacement in mixing bowl or food processor and whip into a puree. Stir completely into gelatin mixture. When blueberry mixture is cool, thick and syrupy, beat until frothy. Fold stiffly beaten egg whites into blueverry mixture. Spoon into 6 serving dishes; refrigerate until set.
