When for example adding the ssh implementation Felix wrote at some point you
will get that situation.

In general, to implement various network protocols you can use an object which
sits between the connection object and the user object. To the connection
object, such an 'inbetween' will act as user object, whereas to the 'real'
user object, it will act as a connection object, and hence has to inherit LIB_CONN
