For the PVP scenario there's nothing keeping the other team from connecting to your ship and messing with Engineering, taking shields off line, initiating Self Destruct, watching where you are, etc.
I recommend requiring a Pin Number in order to connect. The first computer to connect to a ship could have the pin number displayed to allow other consoles to connect. The self destruct widgets can be used to enter the Pin. Course I would think that this would require code changes in EE.
This would be nice to have mostly for online games. That way other people can connect to your game, but not mess with your ship.
Should be a setting in the scenario as this wouldn't helpful for single ship games.
