that's very interesting, but I suspect NTP needs to cope with whatever
network you throw at it. Accuracy and stability will depends very much
on network conditions... NTP algorithms may have to be re-engineered
every so often in order to take into account the latest fashion in
network design as nobody provides networks to suit time synchronisation
requirements (unless you believe IEEE 1588!).
