There's a big difference between synchronization across a LAN you
control vs an internet connection.  For keeping a set of machines
close, a local master setup will keep them closer than each hitting
the pool.  You don't have to have a single point of failure.  You can
use just about any hierarchy you want, up to a self-healing
orphan+manycast mesh.

Cheers,
