If it's never divulged, how can you use it to tell you who sent you the
packet?
For example, suppose I have two servers, A and B. A is talking to a
third server C. I wish to determine if a server B is talking to is that same
server C, or a distinct server, D. How will a session hash help me do that?
On the other hand, a public server ID that is globally unique *will* help me
do that. The source IP won't, because a single machine can have multiple
addresses.
