"Microsoft has done exactly this with BSD code." Yep - their networking stack, to be exact... and its locked down good and tight. That's not open-source, that stupidity on the BSD team's part, and a huge reason why BSD itself never really took off. It was too easy for IBM, MS, and everyone else to simply steal what they needed, bury the credit in a .dll or .so file somewhere, and nothing went back into BSD. ...still think it's a good idea? ;) /P
