In the handler class, self.server refers to the server object, so subclass 
the server and override __init__ to take any additional server parameters 
and store them as instance variables.

import SocketServer

class MyServer(SocketServer.ThreadingTCPServer):
    def __init__(self, server_address, RequestHandlerClass,arg1,arg2):
        SocketServer.ThreadingTCPServer.__init__(self,server_address,RequestHandlerClass)
        self.arg1 = arg1
        self.arg2 = arg2

class MyHandler(SocketServer.StreamRequestHandler):
    def handle(self):
        print self.server.arg1
        print self.server.arg2

if __name__ == '__main__':
    srv = MyServer(('',5000),MyHandler,123,456)
    srv.serve_forever()
