Do I understand this correctly that freeciv would have to the above
paragraph if multicast is used? Independent of what multicast group is
used?

If yes than I think that this is clearly too much. We can't touch the
interfaces of a system. You would need root privileges anyway.

So what about the alternative plan to use broadcast? Seems simpler to
me and will work with the case we discuss here (LAN). For the other
case (finding servers on the internet) we have metaserver.
