The OSG primary focus and expected user base is real-time visualization with such applications you won't run multiple applications at the same time and you'll be using the OSG's native windowing, multi-threading, database paging etc. Out of the box the OSG tries to work as well as it can for this usage model. The OSG isn't just about real-time visualization, even if this is it's primary focus, it does support other usage models as well, but out of the box I wouldn't expect all the design decisions based on the above focus to work as well, what is important is that one can adapt the OSG to work well for these other usage models even if out of the box it doesn't do it perfectly. In the case of Qt usage, perhaps osgQt could provide sublcasses from Viewer/CompositeViewer to help adapt the OSG to work better for a typical Qt users requirements.
