The stored procedures approach gets around having the issue of having to maintain the views, but then you've got a chunk of proprietary code out there that has to be maintained and the code to call the stored procedure has to be woven into the application design. IMNSHO, you have to have a compelling reason before introducing this kind of application design overhead.
Views utilize the standard security model of the RDBMS, not one that has had to be developed from scratch. As long as a rule against "special" versions of views is enforced, changes to the views can be largely, if not totally, automated.
