It should be possible to run a SOAP server as a thread in a GNU Radio
application. The simplest possible soap server looks like this:
- - -
import SOAPpy
     def hello():
          return "Hello World"

     server = SOAP.SOAPServer(("localhost", 8080))
     server.registerFunction(hello)
     server.serve_forever()
- - -

and can be called with the following client code:
- - -
import SOAPpy
     server = SOAPpy.SOAPProxy("http://localhost:8080/";)
     print server.hello()
- - -

Of cause you have to replace localhost with the host name of the
server and the hello()-method with something more meaningful, but
otherwise the code should be very similar.

SOAPpy is availble here: http://pywebsvcs.sourceforge.net/
