You present the concept of n-space rather well srs. However, I do have one suggestion. Instead of a pulse, make the ship create a small black hole into n-space, similar to black holes already in the game. The dimensions are based on the XYZ dimensions of the ship, with z determining how long the portal stays open. This way, the coding would be realitivly easy, as it uses existing calculations to do a different job. Also I believe damaged ships should have a penalty in n-space (structural damage, maybe below a percentage?). And I do think jump drives and cloak/jam, and these n-space drives should have a single stipulation: no activating while a cool down is active on your ship
