Better way of using the services of QWSServer

Dear All,

I am working on embedded hand-held device which has keypad,touch screen,RFid reader,fingerprint sensor.

I want to use the features of QWSServer for my application for sceensaver,keypad etc. I am to created plugin for my custom driver and use it successfully.
my want to implement sensor,RFid as some kind of QWSInputMethod so that I can exploit the services of QWSServer.please give me any idea of implementing this as Qt's input device,or can a client send events to server which can call its our static methods in its process.

Thanks in Advance.
