Act as part of operating system was only needed if you were on windows 2000,
using NT or AD db and on a version of 2006 before .04. It is not needed in
any other case, and should not be used.

   One thing I noticed is that there is a requirement that the user be 
granted rights to "Act as part of the operating system".    In my case, I 
created a separate anonymous user, and the installation program did not 
automatically modify my local security policy.   I haven't done this yet - I

don't know if this is for purposes of service control, or if it will 
eliminate the login prompt also.    Presumably this is still much better 
than granting the anonymous user full administration privileges.

  As you note, it would need to be combined with a security hole to be 
dangerous.  Although there have not been any IIS exploits in the last 
several years, we cannot say there would not be any in the future.  There is

a lot of surface area  - the entire web client application and .NET, as well

as IIS.   Standard layered security might prevent a full server root breakin

if they can gain only privileges granted to an anonymous web application 
user.
