Re: Can this be used for a non-GPL feasibility stu

GPL is GPL and Trolltech cannot prohibit using GPL version for any internal purposes, whatever they are. They are just unhappy when 5 programmers create commercial QT application, then they buy 1 licence, recompile application and release it. Such a behaviour seems legal to me, but a bit unfair, of course.

They can't put restrictions up the GPL, but they can put any restrictions they want on their own license for Qt Commercial. They can say, "Qt Commercial can't be used in the development of an application that has previously been developed by Qt Free Edition without keeping the app open sourced..."

Of course, I've never actually heard trolltech going after someone for doing this...

Yeah, this policy was made to stop this from happening.

Actually, there was recently a discussion on the Qt mailing list covering that topic.

The result was the following:

If parts of an application have been developed using Qt/Free you can't license that application with Qt/Commercial.

This was also confirmed by Dimitri from Trolltech. However, this seems hard to enforce. Still if you have product that uses Qt/Commercial and it somehow turns out that parts of this application have been developed using Qt/Free, you're violating the license terms and should probably call your lawyer ;)
