[Spaceships] ExD Interface & Jump Gates?

[Varyon]

Unless the ship can somehow fold in on itself, like some bizarre spaceship-ouroboros, the Jump Gate would have to detach and stay behind.

If you do this, or if you see a Jump Gate as generating a wormhole outside of the ship - like, it shoots a beam that makes a wormhole a couple meters in front of it - it should work fine. So long as there aren't any weird interactions when you throw such a thing through a wormhole, anyway.
