The timer would likely appear on the transfer tab for each ship you are transferring, you then close the services menu and go about playing the game.I'm calling it right now. If you put a wait timer in front of players, they are simply going to shut the game down and play something else.
Your ships are still getting transferred, it's removing an aspect from the game you no longer have to do ( fetching it yourself ), you can do multiple ships at once.
If this pushes people out of the game .. well .. obviously Elite isn't the type of game they want then.
