Thanks for the clarification.  That makes some sense to me.<p>Also, thank you for the article.  It has made me think quite a lot.  It&#x27;s one of those times where my subconscious is saying, &quot;You should pay attention to this&quot;, but I&#x27;m not quite smart enough to understand what I want to do with it.  It will be fun to puzzle it out for a while ;-)
