    4. Mathias shows how to create a service
    5. Graham confirms with Mathias that each service has a separate shared memory segment, dynamically created
    6. Graham asks if it is possible to create a static setup, which should be possible with modifications
    7. Mathias discusses another pain point in iceoryx1, two threads needed for waitset and socket
      1. iceoryx2 can handle this by getting file descriptor of waitset to attach it to select/epoll
      2. Different terminology in iceoryx1 vs. 2
        1. iceoryx2 publisher does not do any event notification, trigger the notifier manually
    8. Mathias walks through the example event_multiplexing
    9. Mathias shows the iox2 tooling similar to ROS 2 (iox2 --help)
    10. Mathias shows GUI called mission control of their internal reference system
    11. One can see the nodes, CPU, memory, frequency stats, etc.
