Yes, I suggested a member function on the connection because that allows 
you to add an arbitrary number of tracked objects to a connection.  If 
they are passed as parameters to connect, you are either limited to 
tracking a single object (or fixed number with default parameters), have 
to pass the objects in a container, or have to make connect a variadic 
function.
