The thing to keep in mind is that plugins in qt are binary files. That 
means that you have to be a bit careful that e.g. the compiler / the qt 
version used to compile the plugin has to more or less match the one of 
the application. Read http://doc.trolltech.com/4.4/plugins-howto.html 
for the full story.
