A supervisor has to _start_ the process (the MFA invoked by the sup must
do return the pid of the child and must be linked to the child). If you
did a child spec which as the MFA did:

{ok, Pid} = amqp_connection:start(network, Params),
{ok, Pid}

then I think that would work. The child spec would need to indicate the
child is a worker. It might then show up. I think. I might be wrong
though - I've never tried having a child supervised by two parents -
sounds a bit like incest to me.
