Feel free to set something up if you want to talk to me further about
where I am coming from with some of these requirements.
If we can find a way to access some of this sensitive data then for the
more complex server authentication scenarios these requirements aren't
going to leak into the IDM - of course then we introduce the problem of
ensuring access to the sensitive values can be restricted ;-)
