How will scanning work within a party? On a cap ship, will the scanner be able to share results with other players or other ships?

Definitely within their ship. If you're in the same party very likely. They've been talking with matt Sherman the idea of transferring info between ships (working on the Herald). they want players to be able to transfer information. They want to be able to have two ships each scanning an area, and seeing each other's areas, even if there' s a bit of a delay.
