Hello. Thanks! Aeron is uni-directional within a single stream. A Publication sends to Subscriptions. There is no response channel built in. But composing a response channel into an application can be done as easy as using another stream in the opposite direction. Most of the time, it is simply connecting the applications together and sending responses in the correct direction.
