Bobby Woolf gave a fun and edutaining talk on services layer architecture at the Triangle JUG meeting tonight. The title was Patterns for Services Using EJB, but thankfully the talk did not really focus on EJB. Instead Bobby cracked a lot of jokes at Microsoft's expense, dropped Martin Fowler's name a few too many times, and talked about the history of and reasoning behind the layered architectures of the past and the relatively new services layer architectures of today.

Roller uses a service layer architecture, by the way. The Roller Business Tier interfaces (in org.roller.model) constitute the services layer.
