Yum, yum! My wife has made a similar dish with beef ribs in the past.

Tried cooking pork ribs Southern style on a grill yesterday. Wound up charring the sauce quite a bit. It is cooked "indirectly", i.e. the fire is not directly under the meat so it's more like baking. It takes 1 1/2 - 2 hours. It's my fault for not watching the temperature.
