The big worry is does the client also register it in their FLSpew, you see there are a lot commands in the game engine that don't get used. They probably worked in the early betas but after M$ butchered it they are now nothing more than space fillers.
Personally you can keep all of your fancy physics, I've found in a number of mods that fancy flight mechanics just don't work worth a f*ck, CV do you remember that seesawing I mentioned on your forum earlier this year, well Arghs toolkit is the worse case I've ever seen. Every NPC seesaws badly, every multiple class encounter is f*cked as the variations in the ship handling causes them to continualy fall out of formation. Why do you think I never got back to Alcander with his variable cruise speed, it causes the same problems, NPCs just can't control drastic alterations.
The AI is primitive and wasn't designed for what most of you want, yet nobody has redesigned it to handle your alterations, and until someone does your wasting your f*cking time even bothering.
