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
A related talk, Metropolis : Envisioning the Service-Oriented Enterprise (November 2003), is available as part of the Architecture Strategy Series and Pat will anchor the TechEd Architecture track in San Diego with a similar talk (ARC300) .

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 to participate).
