Well, that would be possible, yes. But I think this is the wrong usage of the 
smoke lib. You should link against it if you want to use it. I don't see a 
reason why one would want to do this all with dynamic library loading. 
Moreover this wouldn't be cross-platform, which should also be a goal in times 
of Qt4/KDE4 :)
