Standalone Stratum 1 NTP Server

I will go out on a limb and say that a reduction in the cost of
stratum-1 servers will increase their use across the Internet. The
results of such an increase would be arguably visible, as the current
multi-layer timekeeping system seems to be more-or-less keeping
clocks correct to the point of usefulness, at least from a
layer-4-and-up standpoint.

  The point ought to be made that a dense mesh of stratum-2
  sources is likely more robust/accurate than a single
  stratum-1 source...
