I ended up declaring that InternalPrincipal implements the marker
interface IAttributeAnnotatable, and that allowed me to annotate to
the InternalPrincipal instances. It works because InternalPrincipal
instances reside in the ZODB, but I wonder if it's a good idea. If
it's not, then I'd love to see a recipe on how to use the
PrincipalAnnotation machinery with InternalPrincipal instances.

I'm still wondering about this part...
