We need 'typed' client/user relationships. We should have a hook that defines the allowed types, with extra modules defining their own. We should have 'admin' and 'tech' as basics (where admin can add users and do everything and tech can create sites, for example). 'billing' could be defined in a ubercart module and 'ssh' or 'files' could be available in the ITK module.
There is already code in the modules to manage the type, it's just not in the UI yet (+ we need the hooks).
This follows the work on.
