The article, IBM Workplace programming model overview is an excellent conceptual, yet geeky enough for architects and programmers, explanation of what's going on in this new system. I would say that this is the companion piece to Collaboration in context with IBM Workplace Collaboration Services 2.5 which we authored last May 2005.
If you need to architect a solution on Workplace Collaboration Services or Workplace Services Express, then it's a must-read.
