If they only use it inhouse they can even use the GPL version legally. Because the GPL only forces you to make the source available along with the binary if you give it to someone else (outhouse).

Yes, but acording to Trolltech, you cannot use the open-source version of Qt unless you are pulically distributing the code:

http://www.trolltech.com/developer/faqs/190/

Hence my question of how they can require this and not violate the GPL. Anyway, the reading of the above FAQ answer is a bit vague. Maybe they only "recommend" the commercial license for internal applications.

"Using the Qt Open Source Edition, can I make _non-opensource software_ for internal use in my company/organization?"

Keyword: 'non-opensource software'

"Although it is possible to write open source software for internal use, it is difficult to ensure that such software is used and distributed legally. For example, if your open source software requires any modules that impose conditions on you that contradict the conditions of the GNU GPL, including, but not limited to, software patents, commercial license agreements, copyrighted interface definitions or any sort of non-disclosure agreement, then you cannot distribute it at all; hence it cannot be given to consultants, employees for their personal computers, subsidiaries, other divisions, or even to new owners."

Right here it says that you can write open source software for internal use, just that if you're using any modules their license may contradict the GPL.

Next time please read the link before posting, ok?
