Filling: Meanwhile, in small bowl, sprinkle gelatin over rum; set aside. In large bowl, beat eggs with brown sugar until pale; beat in pumpkin pur? cinnamon, ginger, nutmeg and salt. Transfer to saucepan. Cook over medium heat, stirring constantly, until candy thermometer registers 160°F (70°C), about 6 minutes. Remove from heat.

Add gelatin mixture; stir until melted. Add white chocolate; stir until melted. Scrape into large bowl; refrigerate, stirring occasionally, until slightly colder than room temperature but not set, about 1-1/2 hours.

In separate bowl, whip cream; fold into pumpkin mixture. Fold in one-third of the egg whites; fold in remaining whites. Scrape into crust. Swirl top decoratively. Refrigerate until set, about 4 hours. (Make-ahead: Cover loosely with plastic wrap; refrigerate for up to 2 days.)
