Publish and subscribe multi topics on the same node through different machines
Hi, This is a common topic and I know some resources talking about it. I just want to know some additional information. This is for ROS communication across multiple machines.

They mention in session 4, to establish the communication in the other direction we need to kill the talker and listener, then bring them up on opposite machines. Does it mean one machine can be only either talker and a listener at the time? Can we do both direct at the same time? This is a video about one node publish and subscribe simultaneously.

If I implement it like that can I use the multiple machines method? In this case, I do not need to think which machine is a listener and which machine is a talker anymore right? My application is a Simulator that connects with autonomous software and I use ROS1.
