[Zope-CMF] Dynamic Roles?

[John Waycott]

I have started to set up a CMF/Plone Intranet site for the first time 
and wonder if roles can be determined dynamically or programatically?

For example, I add user metadata for "supervisor". Then, create two 
roles "supervisor" and "subordinate", and then set up some condition to 
indicate when these roles are true.

I know I can set up scripts in the workflow to look into the user 
metadata to determine who my supervisor is, but it seems more elegant 
and simpler to me to think of my supervisor and my list of subordinates 
as roles. It would also mean that once a dynamic role was set up, all of 
the CMF security machinery would then take advantage of it.
