Mr. X has received his compensation when he first sold the item for $30 (or whatever). If he sells his virtual widiget to 1000 people, he's made $30,000. Why should he ask for more just so the buyer can use it in a commercial project? His orilginal selling price is his cut in the profit. If he asks for extra to use the item in a for-profit project, then he's double dipping. Melanie
