The emissions are not subect to the inertial forces that you said
might act to change the length of ... say a invar meterstick
because they are massless.

You can not tell if an emission is from a Helium Neon laser or
some other source moving away from you so there
is nothing special about forces changing the atom's spectral lines.

There are several places in Einsten's railcar narrative where it is
claimed that the notion of "simultaniety" is compromised. Interestily,
you can fire equal cannon from these locations and the projectiles
will collide midway between the muzzles. I'd consider that a good
indication of simultaneous firing... wouldn't you ?

This ensemble looks pretty good.
Primary Atomic Reference Clock in Space (PARCS)
... PARCS, NASA Logo. JPL, NIST, and University of Colorado logos ... PARCS will
fly concurrently with SUMO(Superconducting Microwave Oscillator), ...
http://www.boulder.nist.gov/timefreq/cesium/parcs.htm

Time is a mathematical abstraction that can't be measured.
We simulate it's pasage with mechnisms, natural or manmade.

Einstein switches the ether on and off several time in his SR paper.
Is that consistant ?

I didn't see that explicitly. But if you mean Lornetz invariance, it suffers
the limitations I stated. Just as squaring probabilities for Hilbert space
can give a false notion of the qualities of a process.
Look at a primer on AC circuts. The aparent power in the components
is from the imaginary time. It isn't real.
It's OK to use imaginary axes for
computation. It is incorrect to take them as real phenomena.

I did. Maxwell was good and Weber wasn't evil. ;-)

So what's your explanation why Rudolph can't
give Ms. Clause some information faster that light?
It uses both postulates of SR just the way the revered
professor instructed.
