+   f) Asterisk has a relatively new generic asynchronous event API. While it 
+      has been implemented in several areas of the code base, one place where 
+      it has not been utilized but would make a great fit would be to replace 
+      the legacy code used for generating events on the Asterisk Manager 
+      Interface (AMI).  The first phase of this project would be to go through
+      the code base and generate new generic Asterisk events in places where
+      manager events are generated today.  That means that those events would
+      be available to any part of Asterisk that would be interested in doing
+      something with them in a binary format as opposed to a big string.
+      
+      As time permits, a second phase to this project would be to either write
+      a new socket based interface that exposes the generic event API, or to
+      modify the existing manager interface to use the ast_event API to handle
+      receiving events from inside of Asterisk to send to manager clients.
