In a blender, combine the tomato juice, lime juice, Worcestershire, fish sauce and hot sauce, and blend until smooth.
Mix the salt, chili powder and cilantro, and coat the rim of 4 glasses. Fill the glasses with ice. Fill each glass one-quarter full with the tomato mixture, and then fill the remainder with the beer. Give it a light stir and serve with a lime wedge and a platter of pork.
