Has anyone utilized a network of locally, weakly coupled

for precise timekeeping purposes?
There was a discussion on this list about doing something like filling a
cavern with pendulums in this connection a couple months ago.
Bob York at UCSB and Ron Pogorzelski, a recently retired colleague of
mine at JPL, hav done a lot of work with coupled oscillator arrays.
They're used as a way to do phased array antennas. googling "coupled
oscillator array" will turn up many hits.
Allan had a paper where he had 8 inexpensive crystals coupled with
mixers and a microcontroller. I think it's called the Clever
Temperature Compensated XO or something like that.
