The existence of GPL and non-GPL components presents a problem for anyone who wants combine the best components and give away their work. Larry is a bright guy. He solved that problem - and made his software usable in many situations where it might not have been otherwise. >> I'm not a fan of the GPL because of its viral and divisive nature, >> especially for anything that could be considered library code, and >> because it prevents the distribution of any number of potentially >> useful combinations of components (the current poster child being zfs >> on linux, but the issue has always been obvious).

The purpose has always clearly been to restrict the combination of components that can be distributed as a 'work'. If you are old enough you'll probably remember one of the early invocations was to block distribution of the GPL'd gpm library in something that used RSA encryption code even though the components were all available in source. Except for the case of someone selling software and not wanting better versions to compete, it seems very unattractive. Certainly from a user's perspective, allowing all possible combinations of well-tested, reliable components to be combined sounds better.

First, I don't see how _additional_ uses of a software component are a problem to anyone, but even if that somehow bothers you, a dual license of GPL or CDDL should work while still requiring the source of changes to be available to the author. -- Les Mikesell lesmikesell at gmail.com
