The session was built around a two hour user group talk; admittingly this wasn't my best delivery of the session - I'd blame the 20+ hours of flying to get to TechEd but overall it's an important topic and please dig in further to the code.  Feel free to reach out to me, colin@bowern.com, @colinbowern, if you are interested in some of the specifics.  Code is up at https://github.com/colinbowern/presentations.
