Off of travel for a while now, and I want to thank the serveral of you who responded to my question (both on and off the SI List). The response was substantial and totally positive with the one exception of "let me know more (about the tutorial content)." The responses speak well for our group in that everyone wants to gather more information and opinions about a broad and difficult subject. That's the kind of initiative that keeps technology forging ahead. As a result, I am proceeding with the considerable task of updating my older tutorial in parallel with writeups on my recent findings in new (or at least alternate) modeling techniques.
