Cap't Jeff, get real. If you want to be realistic, there would be a way to tag each K ship so we see FoF like black and white. But without messing up the screen with useless F10 crap, the only way would be to alter the textures. Thats why we have to have seperate model folders for the two sides.
Your suggestion is silly. Call it an IFF tag, or telescopic recognition of fleet insignia flags, the only way to represent it visually in battle would be the texture route... That is all.
Also, FS's giving all the class variants specific defined model variant folders was bad afa sensor warfare and range identification goes. Even at extreme range, you can just hit F4 and see what ship class variant you are facing. That shouldnt be the case till they get within the proper identification range. Thats for purists tho. Most peeps are interested in eye candy. Personally, I agree with corbo that if all we saw were flying boxes, I'd be just as happy.
