In a small bowl, combine the first 7 ingredients. Set aside 1/4 cup for dipping sauce. Pour remaining sauce into a bowl or shallow dish; add the pork and turn to coat. Cover and refrigerate 30 minutes.
Drain pork, discarding marinade. Thread pork slices onto 20 metal or soaked wooden skewers. Place skewers in a greased 15x10x1-in. baking pan. Broil 3-4 in. from heat 3-4 minutes on each side or until meat juices run clear.
Meanwhile, for sauce, combine peanut butter and water in a small bowl until smooth. Stir in lime juice and reserved soy sauce mixture. Serve with skewers.
