The latencies on Ultrazone aren't in the one or two second category, but they 
aren't
all that bad.

It appears, however, that the basal latency is about 50 seconds and that this 
latency
hhas a small discontinuity every 18 hours.  Is the clock on Ultrazone accurate? 
 Is it
being reset every 18 hours (by a crontab(1)-executed ntpdate(1), for example)?

Regards,
Steve Emmerson
