I do just want to make very clear that KSharedDataCache is a *cache* and so it is not a suitable guaranteed storage mechanism, although it is useful as a speedup/memory-saver in various scenarios. QDataStream is a good idea as well for arbitrary binary data, but do not forget to set the version of the QDataStream that you expect in your code to something specific so that you can be guaranteed to be able to read it back out later with a newer Qt version!
