vic and rat both have stats on traffic received from other sites, which you can
use I think. Bear in mind that each site will have its own latency values. vic
has a nice stats section that lets you watch parameters as values and as graphs
over time. I don't have access to vic right at the moment, but on the thumbnail
view select info and rtp-stats or similar, and then click on a term in the
table that pops up to graph it.
Otherwise mtrace way work for you (haven't tried it for a long time). Or at
worst, ping. In theory, in an ideal world, multicast packets will take (much)
the same path as unicast, so ping could give you a hint. Except people nowadays
throttle ping traffic <sigh>.
Hmm, does the beaconserver show latencies/rtts? Requires a bit more effort, but
it's worthwile.
