A second draft of the Subject API 0.1 spec is available at 
http://www.stanford.edu/dept/itss/infrastructure/signet/project/doc/subject-api-spec-0.1-draft-02.html. 
This second draft reflects my attempt to reduce the spec to the core 
functionalities that are needed by Grouper and Signet.

Also, in several working group calls, we've debated over how to uniquely 
identify a subject, i.e. source+id, type+id, and whether this functionality 
should be handled within the Subject API or by the applications which uses 
the API.  Letting applications arbitrarily determine uniqueness may lead to 
interoperability issues.  Programmatically, we need to adopt a consistent 
way to evaluate whether two subjects are equal or not.  I'd like to propose 
that we add to the API an abstract subject class which overrides the 
equals() method.  This method will return true if two subject objects have 
the same source, type, and id.
