I think this is a topic that is still under debate too. I am of the mind that logging in and out is something that needs to be tracked per player; I could log out on my friend's ship, my friend sells the ship, I log back in right on the bridge and steal the ship. Impossibley easy.
The true answer is that it has not been set in stone just yet; I personally feel that there should be some sort of element you log out of at, which then displays that you are logged out there, and if you don't log out at one of these elements then you respawn at your designated res node when you log back in.
