Be careful Lee -- it's a double edged sword you're wielding -- Kerry is a well respected author, one who has advocated, and demonstrated proper attribution for decades -- how do we know you didn't "roll yer own" based upon his original work and then forgot where you got the inspiration?
As stated, I like you both, respect both of your collective works and significant contribution to the knowledge pool, but unless you can prove the plagiarism assertion it remains a really unfortunate gaffe.
