0) Fix implementation of NORM_DATA_FLAG_REPAIR.

1) Implement unicast feedback of NACK messages and server
   re-advertisement for suppressing the unicast feedback.
   (COMPLETED)
   
2) Add mechanism to allow window-based control of NORM server
   transmission rate.  
   
3) Implement TFMCC and/or PGM-CC congestion control mechanisms
   within NORM. (TFMCC COMPLETED)

4) A single squelch message should be sent per repair cycle?
   The squelch works to "synchronize" clients to the server
   repair window.  As the code is currently implemented, the 
   server might generate a squelch per NACK.  This might be OK
   since the occurrence of squelch _should_ be rare.  The 
   debug statistics should keep a count of squelch events.
   (COMPLETED)
   
5) Implement positive acknowledgement mechanism per the NORM spec.
   (COMPLETED - needs more testing)

6) Implement and document simple API to control and access NORM
   features.  (COMPLETED and enhancement in progress)
   
7) Build "norm daemon" using API.

8) JAVA API for NRL NORM Protocol library

9) Correct/complete user guide for "norm" demo app

10) Release wxNormChat project

11) Test, release "naft" (updated "raft") for reliable streaming.

12) Can we eliminate rapid clr norm-cc probing when data is
    not being actively sent? (COMPLETED)
    
13) Fix ns-2 issue when Agent/NORM is attached to ns-2 node ZERO and
    results in a NormNode attempting to be assigned NORM_NODE_NONE as
    a node id.
    
14) IMPORANT: double check ACKing in reponse to watermark polling and
    relation to cc feedback suppression, etc ... watermark acks should
    be unicast and not effect cc feedback?
