Re: Pimping the warp 2 barrier
The "chi" factor also explains why Archer's Starfleet has such an interest in the Vulcan "star charts" -- we can see the stars from Earth! But if the Vulcans have plotted subspace "shipping lanes" and such, then it makes a whole lot more sense. In fact, the recent Star Charts book mentions it.
