InfoWorld's Paul Krill covered Pat's VSLive talk last Thursday:
IT business processes evolving like cities, Microsoft exec says
Official stresses need for standards, service-oriented architectures
http://www.infoworld.com/article/04/03/25/HNhelland_1.html
 
A related talk, Metropolis : Envisioning the Service-Oriented Enterprise (November 2003), is available as part of the Architecture Strategy Series
http://msdn.microsoft.com/architecture/overview/series/ and Pat will anchor the TechEd Architecture track in San Diego with a similar talk (ARC300) http://www.msteched.com/content/breakouts.aspx .

Not mentioned in the InfoWorld coverage is that these talks are useful for architects. They cover SOA concepts including independence, autonomy, and trust and they address problems such as exactly-once execution. The comments and questions that these talks elicit help drive their evolution (visit Pat's blog http://blogs.msdn.com/pathelland/ to participate).
