;; Transition to pub --> sub with pull <-- push
;;
;;   1. client sends request to server via push to the pull port
;;   2. server puts request in queue or processes immediately as appropriate
;;   3. server puts responses from completed requests into pub port 
;;
;; TODO
;;
;; Done Tested
;; [x]  [ ]    1. Add columns pullport pubport to servers table
;; [x]  [ ]    2. Add rm of monitor.db if older than 11/12/2012 
;; [x]  [ ]    3. Add create of pullport and pubport with finding of available ports
;; [x]  [ ]    4. Add client compose of request
;; [x]  [ ]        - name of client: testname/itempath-test_id-hostname 
;; [x]  [ ]        - name of request: callname, params
;; [x]  [ ]        - request key: f(clientname, callname, params)
;; [x]  [ ]    5. Add processing of subscription hits
;; [x]  [ ]        - done when get key 
;; [x]  [ ]        - return results
;; [x]  [ ]    6. Add timeout processing
;; [x]  [ ]        - after 60 seconds
;; [ ]  [ ]            i. check server alive, connect to new if necessary
;; [ ]  [ ]           ii. resend request
;; [ ]  [ ]    7. Turn self ping back on

;; Transition to pub --> sub with pull <-- push

;;
;; TODO
;;
;; Done Tested
;; [x]  [ ]    1. Add columns pullport pubport to servers table
;; [x]  [ ]    2. Add rm of monitor.db if older than 11/12/2012 
;; [x]  [ ]    3. Add create of pullport and pubport with finding of available ports
;; [x]  [ ]    4. Add client compose of request
;; [x]  [ ]        - name of client: testname/itempath-test_id-hostname 
;; [x]  [ ]        - name of request: callname, params
;; [x]  [ ]        - request key: f(clientname, callname, params)
;; [x]  [ ]    5. Add processing of subscription hits
;; [x]  [ ]        - done when get key 
;; [x]  [ ]        - return results
;; [x]  [ ]    6. Add timeout processing
;; [x]  [ ]        - after 60 seconds
;; [ ]  [ ]            i. check server alive, connect to new if necessary
;; [ ]  [ ]           ii. resend request
;; [ ]  [ ]    7. Turn self ping back on
