I had been waiting for this one. Chris Sells' Applied XML Developer's Conference is now scheduled for October 20-21 outside of Portland, OR . Register here: https://www.pluralsight.com/events/devcon/secure/register.aspx (and hurry, the last four of these conferences sold out quickly!) I am all set to go, and really looking forward to it.
