(CER) Cisco Emergency Responder: Some Initial Thoughts Before Configuration

I've never installed Cisco Emergency Responder before.  But I've been asked to look into getting this ready for us and in place.  I'm currently in the process of trying to work through this.  My counterpart has this installed already on a server, and I'm going to try to get this ready for testing.  Its pretty interesting so far, and this is my initial thoughts on how this is going to work.  I worked out my thoughts on my whiteboard.  Ill post more about this topic later on, probably after I get the testing completed, for more about the configuration piece of this. Here should be how this works, based on what I understand so far.
