you're using tp-qt4. Current tp-qt4 git master has the much higher level StreamTubeServer and StreamTubeClient APIs for implementing the Handler which you could use, if you did approval properly in the Approver component. For some reason this hasn't yet been in a public tp-qt4 release, although the API has been merged for a month now (?!?). I'll try to make one happen. -- Br, Olli Salli
