Cool.

I'm not sure what you mean by that.

Last time I checked, neither the principal-permission nor the 
principal-role view were working.

Remember that we were going to change to using 
memento bags. Wanna go ahead and implement http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/MementoBagProposal
(without the registry) and then implement a MementoPrincipalPermission adapter?

You need to provide a principal selection UI using the getPrincipals method
of authentication services. Alternatively, we could provide some way for
authentication services to provide specialized principal selection UIs.

Asking questions is good.

I'm curious why you didn't use a try-state presentation of settings.
