It is my understanding that it is part of your application process.

You can only launch a single app at time with the -qws flag I think. The 
first app acts as the server. Just launch the second app without the 
-qws flag and it will connect to the first app's server.

I think it will lose the server. Try it and find out.

If you need a QWS server to always be running but you wish to start/stop 
your apps several times just make a trivial app that just creates a 
QApplication and launch that with -qws. Launch all of your other apps as 
normal. As long as you leave the original app running you will have a 
QWS server to connect to.

HTH,
