Regarding 2) this is a good point. What will happen if an opponent has occupied an entire island and perhaps even placed a port in the buildable location?

I think that yes it should be possible to attack the port but not the surrounding buildings, for this you'd have to build other fortifications. Which brings up another point that you should in some manner be able to control if you can bring extra wares on the boat so that you are prepared to defend your "invasion". Does this conflict with widelands being non-miltary-game?
