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.
