I realize that this isn't the appropriate use of a service cert.  But 
here's my problem.  I'm setting up a node in a conference room where people 
are used to logging in on the conference room machine with their own 
ID.  Until such time as I (or someone) can modify the certificate system in 
such a way what it pays attention, for instance, to certificates already 
installed in IE (for example), or in Exchange/Outlook, having to require 
that all users have/acquire a certificate is an unworkable situation.  So, 
right now, it's either a service cert, or telling everybody the password to 
the node.

I'm dealing, unfortunately at an executive level here, and impediments like 
having to acquire a certificate can become another reason not to adopt the 

The restrictions in the authorization policy only apply if you have set up 
some rules for the particular venue, though - right?    I haven't had any 
problem in my initial tests in entering venues.

There is also the issue, which I believe is already do-able, but I haven't 
amassed the spare cycles to test, of having this whole system run using our 
own CA and our own certificates.
