Preparation Put oven rack in middle position and preheat oven to 350°F. Stir together crumbs, butter, curry powder, cinnamon, and 2 tablespoons brown sugar in a bowl with a fork until combined well. Reserve 1 tablespoon crumb mixture for garnish and press remaining crumb mixture evenly onto bottom and up side of pie plate. Bake crust 10 minutes, then cool completely in pie plate on a rack, about 20 minutes. Beat together cream cheese, zest, and remaining 6 tablespoons brown sugar in a bowl with an electric mixer at high speed until light and fluffy, about 1 minute. Beat cream with rum in another bowl with cleaned beaters at medium speed until it holds soft peaks. Gently stir one third of whipped cream into cream cheese mixture to lighten, then fold in remaining whipped cream gently but thoroughly. Thinly slice bananas and arrange evenly over bottom of crust. Spread all of cream filling over bananas, then sprinkle reserved crumb mixture over top. Chill pie, loosely covered, 20 minutes.
