The Agenda for GIS Tech is up on the website The green tracks are the more technically oriented sessions, mostly being given by people from the consultancy group.  There’s some good AGS talks, particularly on the second day, I’ve had a preview of some of the demo’s that Matt and Dan are doing in their Ajax\Web 2.0 talk and that should be worth seeing. On the first day I’ll probably stick with the green sessions as well as they all look pretty interesting.
