Pevex in the USA was a one-man company run by Leo Heska, who liked the name "Pewex" from his days living in Poland.  It turns out that Americans pronounce "Pevex" not as "peh-vex" (rhymes with "FedEx"), but rather "pee-vex" (which sounds like someone emptying their bladder while in an angry mood).  For this, and because the Polish-American IT computing connection is already well established, exploited, and served, Leo no longer uses the business names "Pevex" or "Pewex".  Leo still works in IT, and still speaks Polish and loves Poland, and you may still contact him at leo(at)pevex(dot)com.
