Ian,
I won't be at Windex, or listen to your talk. What I wonder is if you make some notes for talk, or film it and do a podcast maybe? Or even just summarize the main points in written form for the rest of us?
I think that yours (you'd be surprised how much I know about you from your posts) is an interesting story. There was a best selling book- how I built coffee republic from my kitchen table- And I think your tale holds similar interest.
Something for you to think about....
