Are you serious? You're writing a library! You think someone might use 
it with Qt! Yes, dumbass, you SHOULD do that! Take a look at some of the 
boost headers (esp. functional, lambda, bind) and THEN bitch about how 
hard it is to write a library.
If it hurts your poor fingers (or eyes), put this somewhere useful (ie. 
detail namespace):
namespace whatever = ::boost::BOOST_SIGNALS_NAMESPACE;
