That's NTPv4 isn't it?
I also prefer to use three peers vs. two. Always an odd number, greater than 1. Assumptions can't be made about the mathematics behind time, but in a reference model, odd numbers are better.
Actually, three is not enough; Mills says at least four. Diversity in manufacturer (and controlling organization if you can spare the cycles) is a big big plus. You may wish to read Dr. Mills' post to comp.protocols.time.ntp in the wake of the TrueTime bug of the 2001->2002 new year: http://groups.google.com/groups?hl=en&selm=3C32924F.994E1D01%40udel.edu ---Rob
