The event topic is: Architecting for Scalable and Usable Web Applications.  The event page is not very specific on who the speaker/s is or are, but since it makes mention of the Central Region Architect Evangelists I can make a safe assumption that Larry Clarkin will be at least somewhat involved in the speaking and presentation roles, aside from being the very participative host he always is at these events.

I'll commit to follow up with my cliff notes review of the event content.
