SL is Pepsi. They use publicly available formulas from upstream in order to create product that is as good as upstreams, but is not *the 100% same* since their production formulas are not ***100%/absolutely*** the same. In this analogy, CentOS is the industrial espionage guy who constantly steals new formulas from upstream in order to create **exact/100%** replicas of upstream product. For better analogy, lets say that acquiring that formula is illegal. So, how do you propose that Pepsi and counterfeit work together. P.S. "counterfeit" is extremely wrong to say for CentOS, but analogy demands clear distinction of persons involved, so I beg all to forgive me for this. Ljubomir
