I agree with Abe's assessment.
I would also like to mention the problem of tactics rather than narrative.
Tactically speaking, Wes, with the numbers the way they are now, someone could get the drop on a single planet or place and begin firing almost instantaniously with no immediate reprecussions. Even if someone were a second, or millisecond too late, the rate of our travel is such that I could warp a Yamataian fleet into orbit of Lor, glass the planet, and there's nobody stopping me except public opinion and - well, I can't say 'nothing', since by and large Doc tends to be paranoid and Osaka is good at writing tech. Still, it's the sword that I proposed to hold at the Lorath throat; Yamatai was less powerful in the region, but still had first-strike capability without any observable bases of operation short of a mobile station.
But the same strategy could easily be used on Yamatai with the current travel times and distances. There isn't a single fortress that a suicide run couldn't breech. It's the Nuclear Cold War, all over again; if one person presses, we all press. Mutually assured destruction.
Slowing these times down would make interstellar warfare make slightly more sense, and less dependant on this sort of strategy.
Although to a large extent "Ships move at the speed of plot" and what I just said above doesn't matter, because it would never, ever come to pass with any sensible GM, it's just an example of how the current system might not make perfect sense as written.
We've updated a lot of things about the site as the member base has grown more intelligent and discerning, and if some people want this to happen for whatever reason, I'm sure it's something that they're planning to use to answer that old question of "Well, we could actually get there in 15 seconds..." I think that was someone else's point though?
