I thought of that later but he follow on thought to _that_ is that warp drive red shift might be so high that the signature would become near zero. I mean the Hubble Constant is only a few tens of miles per second. It's bvecause it adds up over billions of years that it becomes as significant as it does.
<shrug> I've probably caused the summoning of one of the Science Police who will inflict a gedanken experiment on us that proves that his causes time travel. :)
