Stir together all the sauce ingredients in a heavy saucepan. Place over a medium-high heat. Simmer uncovered, stirring occasionally, until thickened and reduced to about 1 ¼ cups, about 25-30 minutes.
Thread about 6 shrimp on to each skewer.
Prepare grill for direct heat cooking, over medium-hot charcoal.
Brush shrimp with vegetable oil and sprinkle with salt.
Lightly oil the grill rack. Grill shrimp, and after 2 minutes, turn them over.
Brush shrimp with some of the sauce, and turn them again. Brush with additional sauce, and grill until just cooked, about 1-2 minutes. Serve with the remaining sauce.
