It is possible to disable Posttroll Nameserver usage for the incoming
messages by starting ``satpy_launcher.py`` with command-line arguments
``-n False -a tcp://<host>:<port>`` where the host and port point to a
message publisher. Multiple publisher addresses can be given by supplying
them with additional ``-a`` switches.
