This is not what the general interpretation of the GPL seems to be with
TrollTech and several other companies. They specifically state that even
when you develop inhouse software with GPL-libraries (Qt in the former
case), you are required to release the code of the application under the
GPL. If this weren't so (and you're the first I hear of that takes this
stance), the GPL would basically be meaningless as a business model to
them, and AFAICT this is also what the FSF tells people.

I'd love to hear Phil Thompson's stance on this as the GPL licensing of Qt
and PyQt has deterred me from creating software using Qt for university
distribution (such as the new interactive testing framework I'm currently
writing). In case in house use is fine with him and them, there's nothing
keeping me from dumping wxPython for PyQt, is there? ;-)
