We are currently running 4.1.8 and are considering the benefits of  
upgrading to the Appliances vs changing vendors.  I tried searching  
for a document that compares the new versions of NAC (4.5, 4.6 and  
4.7) but haven't found anything solid.  What I am trying to find is  
which version would be right for our school.  Im also curious what you  
get in 4.7 that you don't get in 4.6 or 4.5 since they all came out so  
relatively close to each other.

Things I have learned is that somewhere along the line the Agent was  
becoming a service.  If that is true, I assume the admin rights  
requirement to upgrade the agent would no longer be required?   
Secondly, I read in release notes that WIndows 7 would be supported,  
as well as Snow Leopard for Mac, and 64 bit versions of all the  
operating systems.  Lastly, another feature I read about was the  
ability to customize prompts and text the end-user reads throughout  
the login and remediation processes.

If anyone knows of such a document or site, or wouldn't mind  
highlighting and corroborating the enhancements in each version we  
would truly appreciate it.

Thanks in advance for your time.
