Since I originally looked at SONAR I've found a couple reasons to
NOT replace the 'pinger' with SONAR. One is that Squid would lose
the ability to send source pings at ICMP packets. The other reason
is that SONAR only defines the message format between a SONAR server
and client. It does not (yet) define how the metric is calculated.
So, in general, it is not possible to compare two SONAR metrics
from two SONAR servers (for the same destination).
