Today one of my clients was kind enough to call my attention to an excellent article published last month by Arnon Rotem-Gal-Oz, which briefly reviews SOA and BI (ETL, specifically), considers the challenges in trying to resolve a service-oriented business intelligence (SoBI) architecture (network bandwidth costs from polling a service), and, positions the push model of event-driven architecture (EDA) as a way to overcome said challenges. The article is definitely worth the read, particularly as challenges (there's that word again) to conventional thinking on ETL emerge in increasingly service-oriented environments.
