A "Dual Standard" is exactly what it sounds like - it is two "Standard" modules each -1 SM smaller than the ship and it takes up the Front and Center sections of the ship.

Okay, two modules instead of one. Perhaps the description should be changed from “A "Dual Standard" module takes up the entire Front and Center Hull sections,” to “"Dual Standard" modules take up the entire Front and Center Hull sections,” to clarify this.

Right, GM determined. You know, maybe I should stop complaining about sci-fi series that don't predetermine all their tech limits up front.

Think, for instance, the Enterprise-D from Star Trek: The Next Generation. Or the Prometheus Class from Star Trek Voyager.

Or the original Enterprise in the classic series (according to the first Technical Manual and blueprints anyway). Uhmm, am I showing my age?

I don't see why a module couldn't have an ExDI, the main issue with calculating performance is whether or not the ExDI stuffs the mass away into the extra dimension or not. If the SM+1/+9 ship still has the mass of a SM+9 ship then it's going to be extremely difficult for it to be mounted on a SM+1.5 or SM+2 ship, since it'll act like an anchor slowing it down (unless the larger ship also has an ED interface, packing away enough engines to push the SM+1/+9 ship)

The system reduces the effective SM of the vehicle for the purposes of external access (doors, etc.) to it, attacking it, or detecting it; and its effective mass and volume when storing or holding it.

I think that covers normal space operations. How the extradimensional mass/size of an ExDI module would be handled by external Stardrives, Exophase Fields, Parachronic/Time Flux Drives or ExDIs would very much be another "GM determined" decision. ;)
