I don't agree that this should be part of the EJB spec itself. Granularity
of distributed interfaces is germane to Any distributed object environment
(RMI, CORBA, EJB, MTS, etc.).
Rather I see it as an area for best practices to be documented, and for
vendors to automate these best practices with tools.
