I was just thing about this WAN jitter issue myself.  I'm wondering how many
folks put NTP traffic in priority queues?  At least for devices in your
managed IP ranges.  Seems like that would improve jitter.  Would like to
hear about others doing this successfully prior to suggesting it for our
network.
