The best way to do that is on your end, using gproc properties. When the
connection is accepted, register the process with the property and use
the property to send messages to all processes. You don't need to
unregister when the connection ends, gproc does that automatically.
The hackish way to do that would be to call supervisor:which_children on
the ranch_conns_sup supervisor of your listener, but that will slow down
the accepting of new connections, so don't do this if you need high
