Hi Erich and Debian Folks, I had dinner with Pamela Samuelson (Cyberlaw instructor at Berkeley) and Mitchell Baker (Attorney and head of Mozilla) this evening. We discussed the dpkg + get_it issue and various examples of derivation without conventional copying of one work directly into another. Their (highly unofficial) call was "nobody knows". I strongly doubt that any of us are interested in clearing up the law with a test case :-) .
If you ever are in a position to influence Troll Tech, the GPL as an option to their present QPL 1.0 license would be nice. Caldera managed to get them to move to QPL 1.0 from their previous (much worse) license as one of the terms of contract work that Troll was doing for Caldera, so this is not that unlikely. I don't see that they have anything to lose from allowing the GPL. Yes, there are ambiguities in the GPL. What's worse is that they are matched by ambiguities in copyright law, because copyright law pre-dates software and very few software concepts have been incorporated into it to date. Thanks Bruce
