Could you elaborate on what you mean by dynamic?  I haven't used qt 
signals/slots since qt 3, but in those days I believe both the signal and 
slot end had to be in classes derived from QObject, plus have the Q_OBJECT 
macro in their declaration, as well as "slots:" and "signals:" pseudo-access 
specifications for the moc preprocessor to chew on.

thread_safe_signals in the review queue does, although it doesn't have a 
review manager yet.
