The execise was more of a feasability study.

This looks as though it contains all the semantics required for the current
Turbine authorisation model, but is it flexible enough for all future
applications? I'd take a bet that someone can come up with a scenario that
doesnt fit with this model.
I feel the key to providing such a flexible permissions model lies within
the Principal Interface, or at least a re-designed version.
JAAS has many excellent design concepts that would be silly to ignore. Using
these concepts and improving the Principal IF could result in a very
powerful, authorisation system. (like JAAS, but better) ;-)
