Chand, I too was wondering about the size of royalties.
see this in the article in todays Age.
"TFS had revenue of $US1.73 billion in 2003. With royalties tipped to range from 6-25 per cent, of revenues, depending on the industry involved, income could start at $A34 million a year."
....so 25% royalty on 40% of sales of 1.73bil, and this is B4 additional sales...hmmmm
