Are you certain some guy in your raid is spamming your latency to hell and back with his insane addons? Now you can prove it (not that that could ever happen, I think, but hey, it's fun to blame people!)
Broker: CHAT_MSG_ADDON gathers information about the bytes travelling through the addon communication channel and gives you a "high score" list of the top spammers, in addition to average bytes transmitted over the last 10 seconds, and other small statistics.
It is designed to be small and effective, and actually mostly for fun. The data it gathers and displays is fun to watch, at least for me!
The screenshot shows Broker_CMA running on the Blockoland LDB display addon, but of course any capable LDB display addon will do; like NinjaPanel, Fortress, Bazooka, etc. Also note that in the screenshot, I've been online for at most 15 seconds, just long enough to line up the screenshot to the sky and snap it. The display will become a lot more lively during a raid session ;)
