To my reading, this sentence doesn't make sense -- you seem to be saying that the license's license has to be QPL. Is this meant to mean ``Modifications must be licensed under the QPL'' or ``Modifications must be licensed under a license no more restrictive than the QPL'' or ``...no less restrictive than the QPL'' or...? It would seem better to separate this clause into ``Modifications may be made and distributed under the QPL'' and something along the lines of ``The copyright holder (that's trolltech) is granted permission to rerelease the Software (that's anything under the QPL in particular modified versions of Qt) under alternate terms of their choosing.'' Probably with a note that adds that such rereleasing doesn't invalidate the current license (ie the QPL itself). If people want to play nice with trolltech, they just leave the QPL intact. If not, they can then use section 7 to distribute it under the GPL. > 5.

A note as to what "source code" means (as per in the GPL) would probably be good here. > b.

This isn't equivalent to requiring Open Source -- you can, for example, disallow people to charge any money at all for distributing your program, and still link with Qt according to this. That's probably quite reasonable though. If it's not, something along the lines of ``Such software must be made available under a license conforming to the Open Source Definition'' might be usable.
