Depending on how you and Trolltech and Riverbank Computing interpret the
situation, the Qt-specific parts can probably only be considered GPLed.
For users of the GPLed versions of PyQt, this shouldn't pose a problem
as their code would have deal with the GPL license of PyQt regardless.
Users of the non-GPL versions would be in a bind. I believe that
Trolltech discourages developing code using the GPL version, then buying
a license and selling programs. I don't know how they like releasing
open source, GPL-compatible, but non-GPL, Qt-specific code. I don't
think they're likely to answer that question publically, either.
Code that is not Qt-specific, however, can be licensed under whatever
license you like when separate from Qt. It might be easiest just handle
this on a case-by-case basis when people want to use non-Qt pieces of
code. Hopefully, there will only be a handful of groups working on
plotting packages. ;-)
