Indictometer? I like it!
"plugin more clearly telegraph to users when it could potentially be dangerous to let Java code be executed in their browsers (not all the time? – Ed)."
Ed (talking horse or editor... or both?) is right I think ;)
So they went to the trouble of installing pretty lights that indicate the level they indict their own product security. Amusing, but worthless, I'd say, given their stellar track record of Java "security" in the browser.
PS: The wording of could potentially leaves a bit to be desired in the weasel words department. Fortunately, The Reg is definitely not Wikipedia though...
 Yes, lame. Excuse: not enough coffee - not that that necessarily improves things but this is the only excuse I can come up with right now.
