Hmmm... I guess I had a couple too many electric popsicles tonight so my thoughts are a bit clouded... So, if I understand you correctly, you're agreeing that ultimately, a person (or company) couldn't take a GPL'ed piece of software available for free (like Gnucleus) and create a derivative work from it and then charge for that derivative work? Ultimately, that's what I'm trying to make sure of.
