I apologize for not following the original thread closely, but has anyone mentioned The White Rabbit Project? Here's a wiki link. Links from there to CERN, etc. It might be beyond budget, etc.

That paper indicates that one way transfer with noise of a few picosec should be feasible using an IR laser. Especially if only required at night for synchronisation of the timebases of the various telescope/detectors in a stellar intensity interferometer. Atmospheric scintillation should be lower as well as background noise from the sky, sun etc. The other factors like rain, hail, snow, fog etc aren't an issue as these preclude observation of the stars of interest.
