The time it takes light to go, say, 10,000 km is essentially zero. 
100% of essentially zero is still essentially zero, and two times
essentially zero is essentially zero.

I wasn't talking about time lag in the context of orbital
communications.  I was talking about the time lag in intrasystem
communications.  Messages from a meson communicator take just as long
to travel from, for example, one planet to another, as messages from
a laser communicator.  I was referring to that sameness of time lag.
