ok hold the phone you mean Bil paying Steve for person A's product since Steve transformed it to work on Bill's PC? or Bill paying Person A? Because for bill to use that product he would still need to buy it off Person A. Not Steve ... though if person A allows the redistribution of his product by steve and gives steve the ok to profit.... steve may charge the conversion fee but not the actual product fee. As that fee would have to go towards person a for it to be legal.
