It is actually possible to measure the one way speed of light directly.

You need a long axis with two disks at both ends. The disks contain an 
extremely fine grid along the rim. The axis could be spun with very high 
pace and controlled in angular velocity very precisely.

Now a laser is sent along the axis and mirrored down to the rim, than it 
is reflect by the rim and modulated by the pattern there.

Then the beam is sent to the other end of that axis and mirrored down to 
that wheel there and gets modulated by a similar pattern.

Now the axis is spun with higher pace, until the reflected beam (from 
'land') is reflected to 'pits' on the other wheel.

 From this the one way speed of light can be calculated, since the time 
light takes from one wheel to the other is the time it takes for the 
wheel to turn from land to pit (in the above mentioned case). And the 
latter is the inverse to the turns per second of the axis times the 
number of pits along the rim.

And even if the required rotations per second and the number of pits are 
quite high, this could actually be built. Its only a little difficult 
and certainly expensive.
