> I do it because I want anyone that uses that code to share their changes back with me You should be clear that the GPL has no such upstream requirement. Changes only need to be passed on downstream. It's pass-it-on, not give-back. It often works out that upstream gets access to the same channel that receives the changes, but that's not necessarily the case, strictly.
