Plugin suggestion?

[LlewynHouse]

My suggestion would be to have two separate kinds of kiwiship. one that can go up in the air like the current ones, and one that can not. this could be achieved by coding the licences to only be needed to go up or down, this would allow use of normal seafaring ships to all. or perhaps to only be allowed to take wagons or sailing ships up or down two squares to get up hils and such and not for a long period of time (No flying wagons)
