John,
" ... when it is theoretically convenient, ie. inflation, space is presumed to have expanded at far greater than the speed of light."
Not presumed. Calculated. Big difference. The problem that the theory of inflation purports to solve, is the cosmological horizon problem ( i.e., how two extremes of the universe can have been in communication in the distant past, when the distance between them is too great for light to have traveled). It can be seen that Albrecht's program also solves this problem, by making past events dependent on present measure values (equivalent, I think, to Wheeler's delayed choice proposal).
"You miss the point anyway."
I expect that I always will, when I see a contradiction, because I stop before continuing to buy into a propositioon.
"As expansion is proposed, the speed of light is used as an indenpendent measure of the expanding universe,"
No. The speed of light is never a measure independent of space.
" ... given these other galaxies are eventually assumed to move beyond the point of being visible."
Hence, the term "horizon."
"Since it is taking longer for the light to travel between galaxies, that is a stable measure of space and there is just an increased amount of it."
Not necessarily. Perhaps there is just more time. As Hawking explains by the device of imaginary time -- and as I explain by changing the convention of Einstein's 'finite but unbounded' model of general relativity that is finite in time (bounded at the cosmological singularity) to one finite in space (the manifold of the Riemann sphere S^3 with one simple pole at infinity) and unbounded in time. This does not change a single equation of general relativity.
"So what frame determines the speed of light, if it is independent of the expansion of space?"
What I've been trying to get across to you, among others -- is that there is no privileged reference frame in relativity. The speed of light is phenomenological; a measured value. It is not measured independent of space, because neither space nor time independently are physically real.
