When talking to sailors about starting tactics, I often advise that they take a transit on the layline to the signal boat. That way, they know where to turn close-hauled in order to shut out windward boats (without getting shut out themselves). Provided you don't let them get clear ahead of you, you can "close the door" on windward boats well back of the signal boat.
While not "barging" per say, this video shows a boat taking a transit on the layline to the committee boat, "closing the door" well behind the line, and forcing a windward boat to peel off at the start.
