I would say that barbecue is a process and not an appliance. Lots of BBQ places use rotating racks so that the heat is all around.
I agree that broil is heat from above and that grill is from below.
In America. Barbecue originally meant an appliance (actually a bed). In the UK and much of the world it means both the appliance and the process. (And the occasion when we eat it.)
Broil just meant to burn!
