This is probably more a Ferrium thing, but I'd love to see something like the Unreal technique employed for glowpoints, thrusters etc, where 2 ship textures are pre-rendered, one for the light on, shadows and all, and one for the light off. That way blinking glowpoints, thrusters etc would illuminate the ship beautifully, but take up almost no CPU time, though I'm not sure how they cope with more than one light flashing at different intervals
Unreal makes it a little better by using a higher quality than in-game rendering engine to render the texture in UnrealEd though
