Could kSOAP do this?

Hello everyone,
I'm new to kSOAP and SOAP.
I'm working on a new project and need your advice to see if kSOAP would be the answer to my problems.
On iPAQs, under Linux (with J2SE 1.3) each of my wireless network users keep special information relative to those users. So the iPAQs must always be ready to answer SOAP requests on this information. I mean, my web service, as well as the other iPAQs should be able to generate SOAP requests to a continuously listening process on the iPAQ. The listening process would be able to get the requests, and generate the correct replies.
Is it possible to do such a thing by, say, creating a ServerSocket on each iPAQ, that would listen for SOAP Requests and instantiate a class to answer each request with the corresponding reply?
I appreciate all your help.
