I'm speaking again this year at DevTeach 2006 in Montreal May 8th-12th.
I'm doing three sessions this year, one called "VS2005 Data Sources and Data Binding" and a two part session on "Designing Applications for Multiple Smart Client UIs". That one also demonstrates a server architecture that supports windows clients as well as mobile devices against the same centralized data. We'll also discuss occasionally connected scenarios and architecture options we have today and in the future. You can see all the speakers and sessions listed here. Hope you can make it!
