Internal/OpenFlow/Controllers/MultiCtl

 We need to define inter-controller communication. At the basic level controllers can communicate by passing !OpenFlow messages amongst themselves. This is like a not-so-transparent, upside-down version of !FlowVisor.
 
+==== (9/9): ====
+The primary steps of concern seem to be the following:
+
+ 1. create a controller that can connect to other controllers
+ 1. pass messages between them (get one to send something to other) 
+ 1. intercept and use messages (get recipient to act on message)
+ 1. make this symmetric (for request/reply/update)
+
+somewhere along the way, we need to devise a service type message/servicetype codes that can be meaningful. For now it is probably a good sanity test to get two controllers to connect to each other, akin to what !FlowVisor does. 
+
+The easiest approach may be to create a module that opens up its own connection, exporting a "switch service" that handshakes with a remote controller.
