That is exactly the problem I had, I have already checked out kded and 
dcopserver.
You either need to have a X Server running to have an event loop, or you 
may have a QApplication, but only that parts of Qt work that do not rely 
on the event loop.
This limits Qt's fitness for deamons, since it would be a great deal to 
be able to use the sam eIO device classes (for example) your client 
programs use.

Thanks anyway,
