replicating FB architecture?

Hi Hal,

> It depends on what you mean by "stratum 1".

I meant the FB architecture stratum 1 = atomic clock.

Nowadays we can apparently get chip-scale atomic clocks, which are on
the order of an Apple laptop in cost. And there are rumours of even
cheaper molecular clocks.
