Ok I think I read you, but lets say his new commercial product was proprietary; the product costs $100. If the license for his original Inbox2 product was GPL, he would be required to distribute the source code on his new product right? So my point is, if its a BSD license he can integrate that code into the $100 product and not have to share the source code. I'm no software license expert so if I'm mistaken please correct me here.

IANAL either, but I still think he'd be free to use his original code in a commercial product. By releasing under GPL, you give others a limited license to redistribute and modify the software subject to some conditions, but you keep all your rights, and you are free to distribute proprietary versions of the code.

Ooooooohhhh neat, OK that makes GPL a whole lot more attractive then. Assumption destroyed; paradigm expanded. Thank-you.
