As Matthias said, it should be pretty simple to generate your own random queue names. Still, if you want the server to do it for you and be able to provide a custom prefix, you can try patch I attached.

An erlang client that use this "extension" could be something like this:




test_prefix(Prefix) ->
    {ok, Connection} = amqp_connection:start(network, #amqp_params{}),
    {ok, Channel} = amqp_connection:open_channel(Connection),
    #'queue.declare_ok'{queue = Name} 
        = amqp_channel:call(Channel, #'queue.declare'{exclusive = true, auto_delete = true, 
                                      arguments = [{<<"x-name-prefix">>, longstr, Prefix}]}),

See the <<"x-name-prefix">> there.
