Besides the line there are also safety divers in the water with modified lift bags that they can snap onto the diver and inflate- as they have their own bottles.

What actually works out a little bit better is to have the bag clipped onto the line and then just turn the valve on the bottle if their is a problem. This pulls the bag up and since the diver is already clipped to the line it will bring the diver up as well. Divers can be stationed with these bags every 30' and can be clipped in at any point during the dive.

Here's a shot of what one looks like.
