Since I last posted an email on this thread I've spent some more 
time looking at tcpdump while our AG node was running.Our network 
security people want me to describe this as detailed as possible, 
so I would appreciate any comments people might have on the accuracy 
of this information.  Note that I haven't used VNC or Distributed 
PPT on our AG node yet.

Thanks for any help.
