Backdoor instant ship transport.
If the station you are at has a shipyard and the ship type you want transferred, you buy the ship and transport the modules you want. If it's instant then in effect you have instantly transported your ship.
This of course.
The player's ship is nothing more than a collection of modules and a hull. Take the hull out of the equation (if it's available locally) and with instant module transfer you get pseudo instant ship transfer. That's why module transfer must follow the same rule as ship transfer.
