Kerberos for Windows 3.2.3-alpha and Network Identity Manager 2.0

[petesea@bigfoot.com]

I have a few questions about the new Kerberos for Windows (KfW) on MIT's 
website and the new Network Identity Manager (NIM) on Secure Endpoints 
website.

- What's different between KfW-3.2.2 and KfW-3.2.3.alpha on MIT's website? 
Are there any release notes for 3.2.3.alpha?

- At the end of the KfW-3.2.3.alpha install, there's a question:

   Ensure that the Kerberos tickets are available throughout the Windows
   login session

What does this mean?  And how is this setting configured?  I couldn't find 
a difference in what was installed or in the registry depending on if this 
was enabled or not.

- Exactly how "alpha" is 3.2.3?   Based on the dates here:

   http://web.mit.edu/kerberos/dist/kfw/3.2/kfw-3.2.3-alpha1/

It looks like it's been on the website for almost 1.5 years, which seems 
like quite a while... are there plans to release this at some point?

- Does 3.2.3 include the new NIM 2.0 from Secure Endpoints website?

- Can NIM 2.0 (from Secure Endpoints) be installed over top KfW 
3.2.3.alpha?   And if so, is it a wise thing to do?
