I think we have a pragmatic difference of opinion on your first point. I have a difficult time accepting that many people are going to track licenses on separate lines of a file into perpetuity. I'm aware of the Aggregate clause in the GPL, but to apply that you need to get into whether or not various lines are "extensions" of the original work, and it's a beast. I really think that people are best just treating each file as GPL, if you add GPL code to it. As for Linking, I don't think you can legally link to a GPL program, from a non-GPL program. This is why the http://en.wikipedia.org/wiki/GPL_linking_exception http://en.wikipedia.org/wiki/GPL_linking_exception exists. The GPL says that GPL and proprietary code "are not combined in a way that would make them effectively a single program." Stallman's position is that this prohibits both dynamic and static linking. http://fsfe.org/projects/gplv3/torino-rms-transcript.en.html#q2-linking http://fsfe.org/projects/gplv3/torino-rms-transcript.en.html...
