Concerning the second issue on notifying the user seems like a bigger issue than just implementing the feature. When should the user be warned? Which licenses do conflict with each other? How should the user be notified, a popup or just a small red icon somewhere? (For me this sounds too big for GSoC but really interesting).

Well, yes.  How do you think it should be shown?  Propose something, we'd be happy to help refine it.  I think that this is part of the project proposal ;-)

I think it could be a reasonable GSoC if you just focused on the Creative Commons licenses and how they interact.  They're fairly well defined and understood there.  Rights in general has as many cases as there are lawyers in the world, so you'd have a harder time finding out whether "can't show on a billboard" applies to this document.
