Colin Moock ripped off?

From reading one of my other favorite bloggers Keith Peters new review sites, I discovered an interesting piece of software, Xpanel. What it does is trace out messages of a swf when the swf is running outside of flash.
But when I read about the class, the class name it seemed awfully familiar.. it was the Logger Class Colin talks about in his Essential Actionscript 2 book! Even the way it behaves with levels of trace statements, Debug, Info, Warning, Error and Fatal.
I guess this the price you pay when you're an ace actionscripter and write lots of books.
