We just released a great whitepaper that describes MCMS 2002 Technical Architecture in-depth. I highly encourage you to check it out at http://www.gotdotnet.com/team/wsservers/ in the MCMS section.

On a side note, just got back from the east coast. While I enjoyed the easy coast, it feels nice being back to Seattle. I stayed away from work for the most part so I'm ready to go! I also had the opportunity to meet Allan Schweighardt, an MSFT EBiz Expert, in NYC.
