We ended up building a Poll Generator for our dojo activity. We almost got done in the 45 minutes or so that we dojo'd. It was a pretty fun activity, and I'd like to do it again sometime soon.
Also, this was really my first public speaking engagement to our technical community, and let me say it was a blast. Everyone had great things to say, and many great questions were asked too.
I set up a google code repository so you can grab my slidedeck and grab the source for our dojo activity and my demo app.
Maybe next time I'll post before the talk, so I can let people know about it.
Thanks guys for all the great feedback, and thanks to my wife for understanding why I wasn't spending any of my evenings with her this week!
